+" repeat.vim - Let the repeat command repeat plugin maps
+" Maintainer:   Tim Pope
+" Version:      1.0
+
+" Installation:
+" Place in either ~/.vim/plugin/repeat.vim (to load at start up) or
+" ~/.vim/autoload/repeat.vim (to load automatically as needed).
+"
+" Developers:
+" Basic usage is as follows:
+"
+"   silent! call repeat#set("\<Plug>MappingToRepeatCommand",3)
+"
+" The first argument is the mapping that will be invoked when the |.| key is
+" pressed.  Typically, it will be the same as the mapping the user invoked.
+" This sequence will be stuffed into the input queue literally.  Thus you must
+" encode special keys by prefixing them with a backslash inside double quotes.
+"
+" The second argument is the default count.  This is the number that will be
+" prefixed to the mapping if no explicit numeric argument was given.  The
+" value of the v:count variable is usually correct and it will be used if the
+" second parameter is omitted.  If your mapping doesn't accept a numeric
+" argument and you never want to receive one, pass a value of -1.
+"
+" Make sure to call the repeat#set function _after_ making changes to the
+" file.

+1. Intro                                                       *NERDCommenter*
+
+The NERD commenter provides many different commenting operations and styles
+which are invoked via key mappings and a menu. These operations are available
+for most filetypes.
+
+There are also options that allow to tweak the commenting engine to your
+taste.
+
+==============================================================================
+2. Functionality provided                               *NERDComFunctionality*
+
+------------------------------------------------------------------------------
+2.1 Functionality summary                        *NERDComFunctionalitySummary*
+
+The following key mappings are provided by default (there is also a menu
+with items corresponding to all the mappings below):
+
+[count],cc |NERDComComment|
+Comment out the current line or text selected in visual mode.
+
+
+[count],cn |NERDComNestedComment|
+Same as ,cc but forces nesting.
+
+
+[count],c<space> |NERDComToggleComment|
+Toggles the comment state of the selected line(s). If the topmost selected
+line is commented, all selected lines are uncommented and vice versa.
+
+
+[count],cm |NERDComMinimalComment|
+Comments the given lines using only one set of multipart delimiters.
+
+
+[count],ci |NERDComInvertComment|
+Toggles the comment state of the selected line(s) individually.
+
+
+[count],cs |NERDComSexyComment|
+Comments out the selected lines ``sexily''
+
+
+[count],cy |NERDComYankComment|
+Same as ,cc except that the commented line(s) are yanked first.
+
+
+,c$ |NERDComEOLComment|
+Comments the current line from the cursor to the end of line.
+
+
+,cA |NERDComAppendComment|
+Adds comment delimiters to the end of line and goes into insert mode between
+them.
+
+
+|NERDComInsertComment|
+Adds comment delimiters at the current cursor position and inserts between.
+Disabled by default.
+
+
+,ca |NERDComAltDelim|
+Switches to the alternative set of delimiters.
+
+
+[count],cl
+[count],cb    |NERDComAlignedComment|
+Same as |NERDComComment| except that the delimiters are aligned down the
+left side (,cl) or both sides (,cb).
+
+
+[count],cu |NERDComUncommentLine|
+Uncomments the selected line(s).
+
+------------------------------------------------------------------------------
+2.2 Functionality details                        *NERDComFunctionalityDetails*
+
+------------------------------------------------------------------------------
+2.2.1 Comment map                                             *NERDComComment*
+
+Default mapping: [count],cc
+Mapped to: <plug>NERDCommenterComment
+Applicable modes: normal visual visual-line visual-block.
+
+
+Comments out the current line. If multiple lines are selected in visual-line
+mode, they are all commented out.  If some text is selected in visual or
+visual-block mode then the script will try to comment out the exact text that
+is selected using multi-part delimiters if they are available.
+
+If a [count] is given in normal mode, the mapping works as though that many
+lines were selected in visual-line mode.
+
+------------------------------------------------------------------------------
+2.2.2 Nested comment map                                *NERDComNestedComment*
+
+Default mapping: [count],cn
+Mapped to: <plug>NERDCommenterNest
+Applicable modes: normal visual visual-line visual-block.
+
+Performs nested commenting.  Works the same as ,cc except that if a line is
+already commented then it will be commented again.
+
+If |'NERDUsePlaceHolders'| is set then the previous comment delimiters will
+be replaced by place-holder delimiters if needed.  Otherwise the nested
+comment will only be added if the current commenting delimiters have no right
+delimiter (to avoid syntax errors)
+
+If a [count] is given in normal mode, the mapping works as though that many
+lines were selected in visual-line mode.
+

+|'NERDDefaultNesting'|
+
+------------------------------------------------------------------------------
+2.2.3 Toggle comment map                                *NERDComToggleComment*
+
+Default mapping: [count],c<space>
+Mapped to: <plug>NERDCommenterToggle
+Applicable modes: normal visual-line.
+
+Toggles commenting of the lines selected. The behaviour of this mapping
+depends on whether the first line selected is commented or not.  If so, all
+selected lines are uncommented and vice versa.
+
+With this mapping, a line is only considered to be commented if it starts with
+a left delimiter.
+
+If a [count] is given in normal mode, the mapping works as though that many
+lines were selected in visual-line mode.
+
+------------------------------------------------------------------------------
+2.2.4 Minimal comment map                              *NERDComMinimalComment*
+
+Default mapping: [count],cm
+Mapped to: <plug>NERDCommenterMinimal
+Applicable modes: normal visual-line.
+
+Comments the selected lines using one set of multipart delimiters if possible.
+
+For example: if you are programming in c and you select 5 lines and press ,cm
+then a '/*' will be placed at the start of the top line and a '*/' will be
+placed at the end of the last line.
+
+Sets of multipart comment delimiters that are between the top and bottom
+selected lines are replaced with place holders (see |'NERDLPlace'|) if
+|'NERDUsePlaceHolders'| is set for the current filetype. If it is not, then
+the comment will be aborted if place holders are required to prevent illegal
+syntax.
+
+If a [count] is given in normal mode, the mapping works as though that many
+lines were selected in visual-line mode.
+
+------------------------------------------------------------------------------
+2.2.5 Invert comment map                                *NERDComInvertComment*
+
+Default mapping: ,ci
+Mapped to: <plug>NERDCommenterInvert
+Applicable modes: normal visual-line.
+
+Inverts the commented state of each selected line. If the a selected line is
+commented then it is uncommented and vice versa. Each line is examined and
+commented/uncommented individually.
+
+With this mapping, a line is only considered to be commented if it starts with
+a left delimiter.
+
+If a [count] is given in normal mode, the mapping works as though that many
+lines were selected in visual-line mode.
+
+------------------------------------------------------------------------------
+2.2.6 Sexy comment map                                    *NERDComSexyComment*
+
+Default mapping: [count],cs
+Mapped to: <plug>NERDCommenterSexy
+Applicable modes: normal, visual-line.
+
+Comments the selected line(s) ``sexily''... see |NERDComSexyComments| for
+a description of what sexy comments are. Can only be done on filetypes for
+which there is at least one set of multipart comment delimiters specified.
+
+Sexy comments cannot be nested and lines inside a sexy comment cannot be
+commented again.
+
+If a [count] is given in normal mode, the mapping works as though that many
+lines were selected in visual-line mode.
+

+------------------------------------------------------------------------------
+2.2.7 Yank comment map                                    *NERDComYankComment*
+
+Default mapping: [count],cy
+Mapped to: <plug>NERDCommenterYank
+Applicable modes: normal visual visual-line visual-block.
+
+Same as ,cc except that it yanks the line(s) that are commented first.
+
+------------------------------------------------------------------------------
+2.2.8 Comment to EOL map                                   *NERDComEOLComment*
+
+Default mapping: ,c$
+Mapped to: <plug>NERDCommenterToEOL
+Applicable modes: normal.
+
+Comments the current line from the current cursor position up to the end of
+the line.
+
+------------------------------------------------------------------------------
+2.2.9 Append com to line map                            *NERDComAppendComment*
+
+Default mapping: ,cA
+Mapped to: <plug>NERDCommenterAppend
+Applicable modes: normal.
+
+Appends comment delimiters to the end of the current line and goes
+to insert mode between the new delimiters.
+
+------------------------------------------------------------------------------
+2.2.10 Insert comment map                               *NERDComInsertComment*
+
+Default mapping: disabled by default.
+Map it to: <plug>NERDCommenterInInsert
+Applicable modes: insert.
+
+Adds comment delimiters at the current cursor position and inserts
+between them.
+
+NOTE: prior to version 2.1.17 this was mapped to ctrl-c. To restore this
+mapping add >
+    let NERDComInsertMap='<c-c>'
+<
+to your vimrc.
+
+------------------------------------------------------------------------------
+2.2.11 Use alternate delims map                              *NERDComAltDelim*
+
+Default mapping: ,ca
+Mapped to: <plug>NERDCommenterAltDelims
+Applicable modes: normal.
+
+Changes to the alternative commenting style if one is available. For example,
+if the user is editing a c++ file using // comments and they hit ,ca
+then they will be switched over to /**/ comments.
+
+See also |NERDComDefaultDelims|
+
+------------------------------------------------------------------------------
+2.2.12 Comment aligned maps                            *NERDComAlignedComment*
+
+Default mappings: [count],cl   [count],cb
+Mapped to: <plug>NERDCommenterAlignLeft
+           <plug>NERDCommenterAlignBoth
+Applicable modes: normal visual-line.
+
+Same as ,cc except that the comment delimiters are aligned on the left side or
+both sides respectively. These comments are always nested if the line(s) are
+already commented.
+
+If a [count] is given in normal mode, the mapping works as though that many
+lines were selected in visual-line mode.
+
+------------------------------------------------------------------------------
+2.2.13 Uncomment line map                               *NERDComUncommentLine*
+
+Default mapping: [count],cu
+Mapped to: <plug>NERDCommenterUncomment
+Applicable modes: normal visual visual-line visual-block.
+
+Uncomments the current line. If multiple lines are selected in
+visual mode then they are all uncommented.
+
+When uncommenting, if the line contains multiple sets of delimiters then the
+``outtermost'' pair of delimiters will be removed.
+
+The script uses a set of heurisics to distinguish ``real'' delimiters from
+``fake'' ones when uncommenting. See |NERDComIssues| for details.
+
+If a [count] is given in normal mode, the mapping works as though that many
+lines were selected in visual-line mode.

+2.4 Sexy Comments                                        *NERDComSexyComments*
+These are comments that use one set of multipart comment delimiters as well as
+one other marker symbol. For example: >
+    /*
+     * This is a c style sexy comment
+     * So there!
+     */
+
+    /* This is a c style sexy comment
+     * So there!
+     * But this one is ``compact'' style */
+<
+Here the multipart delimiters are /* and */ and the marker is *.
+
+------------------------------------------------------------------------------
+2.5 The NERDComment function                             *NERDComNERDComment*
+
+All of the NERD commenter mappings and menu items invoke a single function
+which delegates the commenting work to other functions. This function is
+public and has the prototype: >
+    function! NERDComment(isVisual, type)
+<
+The arguments to this function are simple:
+    - isVisual: if you wish to do any kind of visual comment then set this to
+      1 and the function will use the '< and '> marks to find the comment
+      boundries. If set to 0 then the function will operate on the current
+      line.
+    - type: is used to specify what type of commenting operation is to be
+      performed, and it can be one of the following: "sexy", "invert",
+      "minimal", "toggle", "alignLeft", "alignBoth", "norm", "nested",
+      "toEOL", "append", "insert", "uncomment", "yank"
+
+For example, if you typed >
+    :call NERDComment(1, 'sexy')
+<
+then the script would do a sexy comment on the last visual selection.

+                                      uncommenting.
+|'NERDRemoveExtraSpaces'|             Tells the script to always remove the

+|'NERDRPlace'|                        Specifies what to use as the right
+                                      delimiter placeholder when nesting
+                                      comments.
+|'NERDSpaceDelims'|                   Specifies whether to add extra spaces
+                                      around delimiters when commenting, and
+                                      whether to remove them when

+3.3 Options details                                    *NERDComOptionsDetails*
+
+To enable any of the below options you should put the given line in your
+~/.vimrc
+
+                                                       *'loaded_nerd_comments'*
+If this script is driving you insane you can turn it off by setting this
+option >
+    let loaded_nerd_comments=1
+<
+------------------------------------------------------------------------------
+                                                    *'NERDAllowAnyVisualDelims'*
+Values: 0 or 1.
+Default: 1.
+
+If set to 1 then, when doing a visual or visual-block comment (but not a
+visual-line comment), the script will choose the right delimiters to use for
+the comment. This means either using the current delimiters if they are
+multipart or using the alternative delimiters if THEY are multipart.  For
+example if we are editing the following java code: >
+    float foo = 1221;
+    float bar = 324;
+    System.out.println(foo * bar);
+<
+If we are using // comments and select the "foo" and "bar" in visual-block
+mode, as shown left below (where '|'s are used to represent the visual-block
+boundary), and comment it then the script will use the alternative delims as
+shown on the right: >
+
+    float |foo| = 1221;                   float /*foo*/ = 1221;
+    float |bar| = 324;                    float /*bar*/ = 324;
+    System.out.println(foo * bar);        System.out.println(foo * bar);
+<
+------------------------------------------------------------------------------
+                                                     *'NERDBlockComIgnoreEmpty'*
+Values: 0 or 1.
+Default: 1.
+
+This option  affects visual-block mode commenting. If this option is turned
+on, lines that begin outside the right boundary of the selection block will be
+ignored.
+
+For example, if you are commenting this chunk of c code in visual-block mode
+(where the '|'s are used to represent the visual-block boundary) >
+    #include <sys/types.h>
+    #include <unistd.h>
+    #include <stdio.h>
+   |int| main(){
+   |   | printf("SUCK THIS\n");
+   |   | while(1){
+   |   |     fork();
+   |   | }
+   |}  |
+<
+If NERDBlockComIgnoreEmpty=0 then this code will become: >
+    #include <sys/types.h>
+    #include <unistd.h>
+    #include <stdio.h>
+    /*int*/ main(){
+    /*   */ printf("SUCK THIS\n");
+    /*   */ while(1){
+    /*   */     fork();
+    /*   */ }
+    /*}  */
+<
+Otherwise, the code block would become: >
+    #include <sys/types.h>
+    #include <unistd.h>
+    #include <stdio.h>
+    /*int*/ main(){
+    printf("SUCK THIS\n");
+    while(1){
+        fork();
+    }
+    /*}  */
+<
+------------------------------------------------------------------------------
+                                                *'NERDCommentWholeLinesInVMode'*
+Values: 0, 1 or 2.
+Default: 0.
+
+By default the script tries to comment out exactly what is selected in visual
+mode (v). For example if you select and comment the following c code (using |
+to represent the visual boundary): >
+    in|t foo = 3;
+    int bar =| 9;
+    int baz = foo + bar;
+<
+This will result in: >
+    in/*t foo = 3;*/
+    /*int bar =*/ 9;
+    int baz = foo + bar;
+<
+But some people prefer it if the whole lines are commented like: >
+    /*int foo = 3;*/
+    /*int bar = 9;*/
+    int baz = foo + bar;
+<
+If you prefer the second option then stick this line in your vimrc: >
+    let NERDCommentWholeLinesInVMode=1
+<
+
+If the filetype you are editing only has no multipart delimiters (for example
+a shell script) and you hadnt set this option then the above would become >
+    in#t foo = 3;
+    #int bar = 9;
+<
+(where # is the comment delimiter) as this is the closest the script can
+come to commenting out exactly what was selected. If you prefer for whole
+lines to be commented out when there is no multipart delimiters but the EXACT
+text that was selected to be commented out if there IS multipart delimiters
+then stick the following line in your vimrc: >
+    let NERDCommentWholeLinesInVMode=2
+<
+
+Note that this option does not affect the behaviour of commenting in
+|visual-block| mode.
+
+------------------------------------------------------------------------------
+                                                *'NERDCreateDefaultMappings'*
+Values: 0 or 1.
+Default: 1.
+
+If set to 0, none of the default mappings will be created.
+
+See also |NERDComMappings|.
+
+------------------------------------------------------------------------------
+                                                           *'NERDRemoveAltComs'*
+Values: 0 or 1.
+Default: 1.
+
+When uncommenting a line (for a filetype with an alternative commenting style)
+this option tells the script whether to look for, and remove, comment
+delimiters of the alternative style.
+
+For example, if you are editing a c++ file using // style comments and you go
+,cu on this line: >
+    /* This is a c++ comment baby! */
+<
+It will not be uncommented if the NERDRemoveAltComs is set to 0.
+
+------------------------------------------------------------------------------
+                                                       *'NERDRemoveExtraSpaces'*
+Values: 0 or 1.
+Default: 1.
+
+By default, the NERD commenter will remove spaces around comment delimiters if
+either:
+1. |'NERDSpaceDelims'| is set to 1.
+2. NERDRemoveExtraSpaces is set to 1.
+
+This means that if we have the following lines in a c code file: >
+    /* int foo = 5; */
+    /* int bar = 10; */
+    int baz = foo + bar
+<
+If either of the above conditions hold then if these lines are uncommented
+they will become: >
+    int foo = 5;
+    int bar = 10;
+    int baz = foo + bar
+<
+Otherwise they would become: >
+     int foo = 5;
+     int bar = 10;
+    int baz = foo + bar
+<
+If you want the spaces to be removed only if |'NERDSpaceDelims'| is set then
+set NERDRemoveExtraSpaces to 0.
+
+------------------------------------------------------------------------------
+                                                                  *'NERDLPlace'*
+                                                                  *'NERDRPlace'*
+Values: arbitrary string.
+Default:
+    NERDLPlace: "[>"
+    NERDRPlace: "<]"
+
+These options are used to control the strings used as place-holder delimiters.
+Place holder delimiters are used when performing nested commenting when the
+filetype supports commenting styles with both left and right delimiters.
+To set these options use lines like: >
+    let NERDLPlace="FOO"
+    let NERDRPlace="BAR"
+<
+Following the above example, if we have line of c code: >
+    /* int horse */
+<
+and we comment it with ,cn it will be changed to: >
+    /*FOO int horse BAR*/
+<
+When we uncomment this line it will go back to what it was.
+
+------------------------------------------------------------------------------
+                                                                *'NERDMenuMode'*
+Values: 0, 1, 2, 3.
+Default: 3
+
+This option can take 4 values:
+    "0": Turns the menu off.
+    "1": Turns the 'comment' menu on with no menu shortcut.
+    "2": Turns the 'comment 'menu on with <alt>-c as the shortcut.
+    "3": Turns the 'Plugin -> comment' menu on with <alt>-c as the shortcut.
+
+------------------------------------------------------------------------------
+                                                         *'NERDUsePlaceHolders'*
+Values: 0 or 1.
+Default 1.
+
+This option is used to specify whether place-holder delimiters should be used
+when creating a nested comment.
+
+------------------------------------------------------------------------------
+                                                             *'NERDSpaceDelims'*
+Values: 0 or 1.
+Default 0.
+
+Some people prefer a space after the left delimiter and before the right
+delimiter like this: >
+    /* int foo=2; */
+<
+as opposed to this: >
+    /*int foo=2;*/
+<
+If you want spaces to be added then set NERDSpaceDelims to 1 in your vimrc.
+
+See also |'NERDRemoveExtraSpaces'|.
+
+------------------------------------------------------------------------------
+                                                         *'NERDCompactSexyComs'*
+Values: 0 or 1.
+Default 0.
+
+Some people may want their sexy comments to be like this: >
+    /* Hi There!
+     * This is a sexy comment
+     * in c */
+<
+As opposed to like this: >
+    /*
+     * Hi There!
+     * This is a sexy comment
+     * in c
+     */
+<
+If this option is set to 1 then the top style will be used.
+
+------------------------------------------------------------------------------
+                                                          *'NERDDefaultNesting'*
+Values: 0 or 1.
+Default 1.
+
+When this option is set to 1, comments are nested automatically. That is, if
+you hit ,cc on a line that is already commented it will be commented again
+
+------------------------------------------------------------------------------
+3.3 Default delimiter customisation                     *NERDComDefaultDelims*
+
+If you want the NERD commenter to use the alternative delimiters for a
+specific filetype by default then put a line of this form into your vimrc: >
+    let NERD_<filetype>_alt_style=1
+<
+Example: java uses // style comments by default, but you want it to default to
+/* */ style comments instead. You would put this line in your vimrc: >
+    let NERD_java_alt_style=1
+<
+
+See |NERDComAltDelim| for switching commenting styles at runtime.
+
+==============================================================================
+4. Key mapping customisation                                *NERDComMappings*
+
+To change a mapping just map another key combo to the internal <plug> mapping.
+For example, to remap the |NERDComComment| mapping to ",omg" you would put
+this line in your vimrc: >
+    map ,omg <plug>NERDCommenterComment
+<
+This will stop the corresponding default mappings from being created.
+
+See the help for the mapping in question to see which <plug> mapping to
+map to.
+
+See also |'NERDCreateDefaultMappings'|.
+
+==============================================================================
+5. Issues with the script                                      *NERDComIssues*
+
+
+------------------------------------------------------------------------------
+5.1 Delimiter detection heuristics                         *NERDComHeuristics*
+
+Heuristics are used to distinguish the real comment delimiters
+
+Because we have comment mappings that place delimiters in the middle of lines,
+removing comment delimiters is a bit tricky. This is because if comment
+delimiters appear in a line doesnt mean they really ARE delimiters. For
+example, Java uses // comments but the line >
+    System.out.println("//");
+<
+clearly contains no real comment delimiters.
+
+To distinguish between ``real'' comment delimiters and ``fake'' ones we use a
+set of heuristics. For example, one such heuristic states that any comment
+delimiter that has an odd number of non-escaped " characters both preceding
+and following it on the line is not a comment because it is probably part of a
+string. These heuristics, while usually pretty accurate, will not work for all
+cases.
+
+------------------------------------------------------------------------------
+5.2 Nesting issues                                            *NERDComNesting*
+
+If we have some line of code like this: >
+    /*int foo */ = /*5 + 9;*/
+<
+This will not be uncommented legally. The NERD commenter will remove the
+"outter most" delimiters so the line will become: >
+    int foo */ = /*5 + 9;
+<
+which almost certainly will not be what you want. Nested sets of comments will
+uncomment fine though. Eg: >
+    /*int/* foo =*/ 5 + 9;*/
+<
+will become: >
+    int/* foo =*/ 5 + 9;
+<
+(Note that in the above examples I have deliberately not used place holders
+for simplicity)
+

+2. Description                                   *yankring-description*
+
+Vim already maintains a list of numbered registers containing the last 9
+deletes.  These previous deletes can be referenced using [register]p, so
+"1p will paste the last delete, "2p the 2nd last delete.  For more
+information see |quote_number|.
+
+Vim does not provide any mechanism to reference previously yanked text.
+In Emacs this feature is called the "kill ring".
+
+The YankRing plugin allows the user to configure the number of yanked
+and deleted text.  After text has been pasted, it can be replaced with
+a previous value from the yankring.
+
+As of version 3.0, the yankring's content will persist (by default)
+between starting and stopping Vim.
+
+The plugin can be toggled on and off, and supports:
+   Ranges
+   Registers
+   Counts
+   All visual modes
+   All motions
+   All text-objects
+
+If you have any suggestions for the improvement of this plugin, see the
+yankring.vim file for my email address.  Suggestions / bug reports are
+always welcome.
+
+For details on the changes between versions see |yankring-history|.
+
+==============================================================================
+3. Configuration                                 *yankring-configure*
+
+The YankRing allows the user to choose which keys are to be assigned to
+the various commands.  By default, the YankRing chose keys identical
+with Vim's standard behaviour/keys.
+
+3.1 Global Variables                             *yankring-globals*
+
+You can customize the YankRing by setting various global variables in
+your |.vimrc|.
+>
+    yankring_max_history
+<       Default: 100
+        Controls how many elements to save in the yankring. >
+            let g:yankring_max_history = 100
+    yankring_min_element_length
+<       Default: 1
+        If the yanked element has a length less than this value
+        if will not be added to the YankRing.  This can be useful if
+        you want to bypass single letter deletes by adding the
+        following to your .vimrc: >
+            let g:yankring_min_element_length = 2
+    yankring_max_element_length
+<       Default: 1048576 (1M)
+        Will truncate a new entry to the specified maximum.  If
+        g:yankring_max_element_length is set to 0, there is no limit. >
+            let g:yankring_max_element_length = 4194304 " 4M
+    yankring_max_display
+<       Default: 500
+        When the YankRing window is opened, each element is displayed on a
+        separate line.  Since each yank could be very large, the display of
+        the element is limited to the above default.  >
+            let g:yankring_max_display = 70
+    yankring_enabled
+<       Default: 1
+        If you do not want to YankRing enabled by default, set this
+        variable in your |vimrc|. >
+            let g:yankring_enabled = 0  " Disables the yankring
+    yankring_persist
+<       Default: 1
+        If you have enabled the storing of global variables in the |viminfo|
+        file, the YankRing will be default persist the contents of the ring
+        between starting and stopping Vim.  To disable this feature: >
+            let g:yankring_persist = 0
+    yankring_share_between_instances
+<       Default: 1
+        By default, any instance of Vim will share the same yankring
+        history file.  But if want each instance to have their own history
+        you can set this option to 0.  Setting g:yankring_persist = 0 and
+        g:yankring_share_between_instances = 0 will ensure no 2 instances
+        of Vim share the same YankRing history AND the history is not
+        remembered the next time Vim is started. >
+            let g:yankring_share_between_instances = 0
+    yankring_dot_repeat_yank
+<       Default: Based on the Vim cpoption setting
+        By default Vim will not repeat (using '.') yanking of text.  This can
+        be controlled via the |'cpoptions'| setting.  The YankRing now respects
+        the cpoptions setting, if 'y' is included and you press '.', the
+        previous yank command is repeated and added to the yankring.
+        You can also add this behaviour by setting this in your |vimrc|: >
+            let g:yankring_dot_repeat_yank = 1
+    yankring_ignore_duplicate
+<       Default: 1
+        Duplicates will not be added to the YankRing by default.  If a
+        duplicate is found, that element will be moved to the top of the
+        yankring.  This can be controlled by setting this in your |vimrc|: >
+            let g:yankring_ignore_duplicate = 0
+    yankring_map_dot
+<       Default: 1
+        If the '.' (repeat) command should be mapped by the yankring.  Since
+        most of the normal commands yy,dd,dw,... are mapped by the yankring,
+        if g:yankring_map_dot is false the . operator will not repeat these
+        operations.  The YankRing tracks several of the internal Vim registers
+        and decides whether an action was the result of the YankRing or an
+        action outside of it.  If the previous action was a result of the
+        yankring, it will be executed again.  If it was an action outside of

+        the original buffer.  This option can be toggled from within the
+        YankRing buffer by pressing [a].  The YankRing buffer status line
+        visually indicates where auto close is enabled or disabled.  There are
+        many times where you need to paste (or delete) many items from the
+        yankring.  Pressing [a], disables auto close, allows you to paste many
+        items, and finally you can press [a] to re-enable auto close, followed

+<       Default: 0
+        Vim already maintains a list of numbered registers containing the last

+<       Default: 'g~ gu gU ! = gq g? > < zf g@'
+        There are a number of Vim operations which do not change any
+        registers, and therefore should not be captured by the yankring.
+        This list is used to ignore the appropriate operators.
+        You can put the following in your |vimrc| >
+            let g:yankring_ignore_operator = 'g~ gu gU ! = gq g? > < zf g@'
+    yankring_history_dir
+<       Default: $HOME
+        The YankRing stores the text in a file.  This global variable
+        allows you to customize where the file(s) will be stored.
+        You can put the following in your |vimrc| >
+            let g:yankring_history_dir = '$VIM'
+    yankring_history_file
+<       Default: 'yankring_history'
+        The history filename prefix can be controlled by setting this

+            let g:yankring_history_file = 'my_yankring_history_file'
+    yankring_clipboard_monitor
+<       Default: 1
+        When flipping between applications I find I often copy text
+        and attempt to use it inside of Vim.  This is typically easy
+        by simply using "+p, but there are times when I will repeatedly
+        want to use the same text later on.  By default, the YankRing
+        will detect when Vim regains focus and check if the clipboard
+        has changed since it last checked.  If so, it will add the contents
+        of the clipboard to the YankRing.  To disable this feature
+        you can put the following in your |vimrc| >
+            let g:yankring_clipboard_monitor = 0
+    yankring_paste_check_default_buffer
+<       Default: 1
+        If the default register has changed without the YankRing registering
+        the change the YankRing will paste the top item from the history
+		rather than what is currently in the default register.
+        This option allows you to control the behaviour.  Plugins can
+        intentionally change the default buffer which the YankRing has
+		no way to noticing.  To disable this feature you can put the following
+		in your |vimrc| >
+            let g:yankring_paste_check_default_buffer = 0

+3.2 Default Keys                                 *yankring-mappings*

+
+        With the introduction of some new features in Vim 7.2 it is no longer

+        The yankring_n_keys only lists actions which an omap cannot be used.
+        Using the yankring_separator, the above list is parsed and
+        individual mappings are created.  For each of the above normal
+        commands the YankRing will include the text those commands
+        acted upon.   There are many ways to accomplish the same result

+        If you do not want to open the YankRing window to choose your
+        selection, then you can paste (as usual) then use a YankRing
+        mapping to cycle through items in the YankRing.  This is especially
+        useful if you know you recently used the text you are looking for.
+        If you wish to cycle through the yankring, replacing the previously
+        pasted text with the previous yanked text you can repeatedly press
+        <C-P> (or whatever keystroke you choose to map it to).  This map
+        moves backwards through the yankring, so you will retrieve your
+        most recent yank.
+
+        I prefer not to use <C-P> since I like using that key to cycle

+
+3.3 Customizing Maps                             *yankring-custom-maps*
+
+The YankRing plugin uses the yankring_n_keys global variable to create
+a number of defaults maps.  The maps are of the form: >
+    nnoremap Y  :<C-U>YRYankCount 'Y'<CR>
+<
+When capital Y is pressed, the YankRing will execute 'Y' and capture the
+output from Vim.  But there are cases where you do not want the default
+behaviour of Vim, since you have customized some of these maps.
+
+In this case, I usually map Y to be |y$|, which makes it consistent with
+the |D| and |C| operators.  The way yankring_n_keys works does not allow
+me to customize this behaviour.  Since many people may like to customize
+the behaviour of these maps the YankRing will check to see if a
+function called YRRunAfterMaps() exists.  If it does, it will call
+this function after it has created the maps.  So in my case, I created
+the following function in my |vimrc|: >
+    function! YRRunAfterMaps()
+        nnoremap Y   :<C-U>YRYankCount 'y$'<CR>
+    endfunction
+<
+You can do anything you need in this function.  >
+        nnoremap Y   :<C-U>YRYankCount 'y$'<CR>
+<
+This line remaps Y (which the user presses) to the YRYankCount command.  The
+YRYankCount tells Vim to execute y$ instead.
+
+
+==============================================================================
+4. Using the YankRing Window:                    *yankring-window*
+
+This is a new feature as of the 2.0 release.  The YankRing uses a
+separate split buffer to display the yankring.  There are many buffer
+specific maps that allow you to operate over the various elements from
+within the yankring.
+
+To display the YankRing buffer you can issue the :YRShow command.  For
+convience you can map a key, <F11>, to this command: >
+	:nnoremap <silent> <F11> :YRShow<CR>
+
+Status line~
+The first line in the YankRing window is the status line. >
+    AutoClose=1;ClipboardMonitor=1;Cmds:p,P,d,r,s,a,c,u,q,<enter>,<space>;Help=?
+<
+Help=?, pressing [?] will toggle the display of available commands the
+yankring window supports.  Pressing [?] again will remove the additional
+items.
+
+AutoClose=1 indicates the window will close when an action is performed
+against elements within the yankring.  If you wish to perform multiple
+yankring operations press [a] to toggle the auto close feature off.  Use the
+commands below and when finished you can press [a] to toggle auto close on and
+press [q] to close the window.  The Cmds displayed are simply reminders of
+the available keys.
+
+ClipboardMonitor=1 indicates the YankRing will monitor the clipboard (+)
+during Focus change events.  If the clipboard has changed since the YankRing
+last checked, the contents are added to the YankRing.  Pressing [c] allows
+you to quickly toggle this setting since it may not be useful at times.
+
+YankRing window key list~
+The following table lists the description of the keys that can be used
+in the YankRing window.
+
+  Key           Description~
+  p             Puts text after the cursor.  In visual mode, all elements
+                selected will be pasted.
+  P             Puts text before the cursor.  In visual mode, all elements
+                selected will be pasted.
+  gp            Just like "p", but leave the cursor just after the new text.
+  gP            Just like "P", but leave the cursor just after the new text.
+  <CR>          Just like "p".
+  <Enter>       Just like "p".
+  <2-LeftMouse> Just like "p".  Normal mode only.
+  d             Removes the element from the yankring.  In visual mode all
+                elements selected will be removed.
+  r             Just like "p", but in visual mode if many lines are selected
+                it will paste these in reverse order.
+  s             Prompts you for a regex to search the YankRing and display
+                only matching items.
+  a             Toggles the g:yankring_window_auto_close setting.
+  u             Updates the YankRing window.
+  q             Closes the YankRing window.
+  <Space>       Toggles the width of the vertical window by the
+                g:yankring_window_increment setting.
+  ?             Toggles the display of the help.

+
+==============================================================================
+5. Commands:                                     *yankring-commands*
+
+The predefined mappings call some specific commands with special parameters.
+If you are going to create additional maps, it is important you mirror
+the same parameters.  Most of these commands have been made obsolete by
+the YankRing window, since it incorporates the functionality below, but
+through maps against a buffer, instead of commands.  This makes it much easier
+to use.
+
+
+5.1  YRToggle                                    *YRToggle*
+         Allows you to enable and disable the YankRing quickly.  This
+         command will remove the default maps and recreate them.
+
+         Examples: >
+            :YRToggle    " Toggles it
+            :YRToggle 1  " Enables it
+            :YRToggle 0  " Disables it
+<
+
+5.2  YRClear                                     *YRClear*
+         Clears all elements from the yankring.
+         See also |YRClear-example|.
+
+
+5.3  YRShow                                      *YRShow*
+         Similar to |:register|, will display all the entries in the yankring.
+         The element at the top will be the next element pasted from the
+         yankring.
+
+         Examples:  >
+            :YRShow     " Shows all entries in the yankring
+
+            --- YankRing ---
+            Elem  Content

+            3     three^@
+            4     two^@
+            5     one^@
+<
+
+5.5  YRGetElem                                   *YRGetElem*
+        This command has two modes.  If no parameters are provided, it
+        becomes interactive.  It uses YRShow to display the list and
+        allows you to choose which element to paste.  If a parameter
+        is supplied it will paste that element from the yankring.  If the
+        number specified is outside of the YankRing an error is returned.
+        You may want to create a separate mapping for this call. >
+            nnoremap <silent> <Leader>yr :YRGetElem<CR>
+<       See also |YRSearch|.
+
+        Examples:
+            Assume there are 10 elements in the YankRing and element 6 is
+            at the top of the ring. >
+            :YRGetElem     " Interactive mode, you choose from a list
+            :YRGetElem 4   " Will paste element 5.
+            :YRGetElem 12  " Will paste element 6.
+            :YRGetElem 99  " Error, invalid choice is reported
+            :YRGetElem 0   " Error, invalid choice is reported
+
+
+5.6  YRGetMultiple                               *YRGetMultiple*
+        Will paste many elements from the YankRing in one command.
+        If the number specified is 1 or less, it is assumed you want
+        just the current element pasted.  If the number specified is
+        greater than or equal to the number of elements in the yankring,
+        it is assumed you want all elements pasted.  If a ! is included
+        as part of the command, paste the items in reverse order.
+        See the |yankring-tutorial| for more examples.
+
+        Examples:
+            Assume there are 10 elements in the YankRing. >
+            :YRGetMultiple  4   " Will paste elements 1,2,3,4
+            :YRGetMultiple! 4   " Will paste elements 4,3,2,1
+            :YRGetMultiple      " Will paste element  1
+            :YRGetMultiple  12  " Will paste elements 1,2,...,10
+            :YRGetMultiple  99  " Will paste elements 1,2,...,10
+            :YRGetMultiple  0   " Will paste element  1
+
+
+5.7  YRPush                                      *YRPush*
+         Allows the user to "push" additional entries into the yankring.
+         If you yanked text via a key mapping which does not use the
+         YankRing (or there is text on the clipboard) you can use this
+         command to add the text to the yankring.
+
+         Examples: >
+            :YRPush      " Push the "  register's contents
+            :YRPush '*'  " Push the "* register's contents (clipboard)
+            :YRPush '+'  " Push the "+ register's contents (clipboard)
+            :YRPush 'a'  " Push the "a register's contents
+<           See also |YRPush-example|.
+
+
+5.8  YRPop                                       *YRPop*
+         Allows you to pop any elements from the yankring.  If no parameters
+         are provided, the 1st element is removed from the yankring.  The
+         command optionally takes a second parameter to specify how many
+         elements to pop.  The default value is 1.
+
+         Examples: >
+            :YRPop      " Removes the highest numbered element from the
+                          yankring
+            :YRPop 3    " Removes the 3rd element from the yankring
+            :YRPop 3,5  " Removes 5 elements from the YankRing beginning
+                          at element 3
+<           See also |YRPop-example|.
+
+
+5.9  YRYankCount                                 *YRYankCount*
+         This command has the most mappings created for it.  If you are
+         in normal mode and you are not specifying a range, this command
+         will add the text to the yankring.
+
+         The goal of this command is to allow the YankRing to be integrated
+         as seamlessly as possible with Vim.  So it supports counts and
+         registers.  If you create a mapping to it, you must pass as a
+         parameter the action you want Vim to perform.  You could do the
+         following: >
+            nnoremap \test  :<C-U>YRYankCount 'dd'<CR>
+<        This map is executed when you hit the '\test' keystrokes, but
+         it will actually delete the current line and add it to the
+         yankring.
+
+         The following are the default mappings: >
+            nnoremap yy  :<C-U>YRYankCount 'yy'<CR>
+            nnoremap dd  :<C-U>YRYankCount 'dd'<CR>
+            nnoremap yw  :<C-U>YRYankCount 'yw'<CR>
+            nnoremap dw  :<C-U>YRYankCount 'dw'<CR>
+            nnoremap ye  :<C-U>YRYankCount 'ye'<CR>
+            nnoremap de  :<C-U>YRYankCount 'de'<CR>
+            nnoremap yiw :<C-U>YRYankCount 'yiw'<CR>
+            nnoremap diw :<C-U>YRYankCount 'diw'<CR>
+            nnoremap Y   :<C-U>YRYankCount 'Y'<CR>
+            nnoremap D   :<C-U>YRYankCount 'D'<CR>
+            nnoremap y$  :<C-U>YRYankCount 'y$'<CR>
+            nnoremap d$  :<C-U>YRYankCount 'd$'<CR>
+            nnoremap yG  :<C-U>YRYankCount 'yG'<CR>
+            nnoremap dG  :<C-U>YRYankCount 'dG'<CR>
+<
+         Examples:
+                yy - Adds the current line to the yankring.
+                dd - Adds the current line to the YankRing and deletes it.
+               5yw - Adds 5 words to the yankring.
+              "ade - Deletes the word, and puts it into both the yankring
+                     and the "a register.
+            10"zyy - Places 10 lines into both the YankRing and the "z
+                     register.
+            See also |yankring-tutorial|.
+
+
+5.10 YRYankRange                                 *YRYankRange*
+         This command by default is only called in visual mode.  All
+         visual modes (|characterwise-visual|, |linewise-visual|,
+         |blockwise-visual|) are supported.  Any visually selected text
+         is added to the yankring.  You can also call this command
+         directly using a range.
+
+         Examples:
+            Visual mode
+            -----------
+            Press v (to enter visual mode), highlight want you want,
+            press y (to yank the selected area).
+            Repeat using V and Control-V.
+
+            Normal mode
+            ----------- >
+            :5,20YRYankRange   " Will yank lines 5-20 into the yankring
+            :5,20YRDeleteRange " Will delete lines 5-20 and add them to
+                                 the yankring
+<           See also |YRYankRange-example|.
+
+
+5.11 YRDeleteRange                               *YRDeleteRange*
+         This command is identical to YRYankRange, except the range is
+         also deleted.
+
+
+5.12 YRPaste                                     *YRPaste*
+        This command will paste elements from the yankring.  By default it has
+        been mapped to p and P to match Vim's native key strokes.  The text
+        pasted is exactly what was yanked, including newline characters and
+        blockwise-visual mode behaviours.  It supports counts and registers.
+
+        Examples:
+            p   " Paste the current element from the YankRing after the cursor
+            P   " Paste the current element from the YankRing before the cursor
+           5p   " Paste the current element from the YankRing after the cursor
+                  5 times
+          "ap   " Ignore the YankRing and paste the contents of register "a
+         5"ap   " Ignore the YankRing and paste the contents of register "a
+                  5 times
+            See also |yankring-tutorial|.
+
+
+5.13 YRReplace                                   *YRReplace*
+        The purpose of the YankRing is to gain access to previously yanked
+        (or deleted) elements.  This command will replace the previously
+        paste  with a different entry from the yankring.
+        By default, I choose <C-P> (P for previous) to replace the last paste
+        while moving backwards through the yankring.  <C-N> (N for next)
+        replaces the last paste while moving forward through the yankring.
+
+        Examples:
+            See the |yankring-tutorial| for examples.
+
+
+5.14 YRMapsCreate                                *YRMapsCreate*
+        This public function is responsible for creating the maps which
+        enable the yankring.  This function is called by the YRToggle
+        command.
+
+
+5.15 YRMapsDelete                                *YRMapsDelete*
+        This public function removes the YankRing maps and disables
+        the yankring.  This function is called by the YRToggle command.
+
+
+5.16 YRSearch                                    *YRSearch*
+        This command is similar to |YRGetElem|.  The command takes
+        one parameter which is a regular expression.  Similar to
+        YRGetElem, it will display all items in the YankRing that match
+        the regular expression.  It is also interactive, and will
+        prompt you to enter which match you wish pasted.
+        See also |YRSearch-example|.

+6. Tutorial                                      *yankring-tutorial*
+
+To understand how to use the yankring, the following example will
+demonstrate the various features.  Assume you have created the following
+mapping: >
+    nnoremap <silent> <F11> :YRShow<CR>
+<
+    Assume we have this buffer: >
+        one
+        two
+        three
+        four
+        five
+<                                                *YRShow-example*
+     Now yank (yy) each line separately starting at line 1.
+     Display the contents of the YankRing by executing the command
+     YRShow, or pressing <F11>.  The contents of the YankRing is
+     displayed in a new buffer.  The size, location and type of buffer
+     is configurable via various options.  See section 3 for more details. >
+        :YRShow or F11
+            --- YankRing ---
+            Elem  Content
+            1     five^@
+            2     four^@
+            3     three^@
+            4     two^@
+            5     one^@
+<    Since we yanked the text starting at line 1 and finishing at
+     line 5, the most current YankRing element is the last one, the
+     contents of line 5.  "five^@" is displayed, the "^@" is a
+     newline character (since we issued a "yy").
+
+                                                 *yankring-window-example*
+     At this point, you have two options.  You can choose which element
+     from the YankRing you wish to paste and press <CR> or 'p' or 'P'
+     and a variety of other options, see |yankring-window|. After pressing
+     the key, the YankRing window will close (default behaviour).  Pressing
+     '?' will display additional help for the commands that are active within
+     the YankRing window.  Pressing '?' will toggle the help.
+
+     You do not need to interact with the YankRing using the YankRing window.
+     Using the window makes many tasks must easier, but for speed using some
+     of the other maps can be preferrable if you know what you have yanked /
+     deleted recently.  It was designed to work with Vim in the usual manner.
+     You can press, 'p', to paste the last item in yanked or deleted.
+
+     Close the YankRing window by pressing 'q' or F11 (which toggles it).
+
+                                                 *YRReplace-example*
+     Now, go to the end of the file and press 'p'.  The resulting
+     buffer appears as: >
+        one
+        two
+        three
+        four
+        five
+        five
+<
+     Assume you did not want 'five", but a different entry from within the
+     yankring.  <C-P> moves backwards through the yankring, it will replace
+     the previous pasted text with a different item from the yankring.  This
+     allows you to quickly iterate through different elements.  <C-P> is the
+     default mapping, this can be user defined. See the following options for
+     more details: >
+        yankring_replace_n_nkey, yankring_replace_n_pkey
+<
+     After pressing <C-P> the buffer results in: >
+        one
+        two
+        three
+        four
+        five
+        four
+<    Now press 2<C-P>.  This would be the same as pressing
+     <C-P> two times in a row.  This results in: >
+        one
+        two
+        three
+        four
+        five
+        two
+<    Now press <C-N> to move forwards through the yankring,
+     this results in: >
+        one
+        two
+        three
+        four
+        five
+        three
+<    Display the contents of the yankring. >

+            4     two^@
+            5     one^@
+<
+    Now lets yank some text with a key stroke that has not been
+    mapped to the yankring.  Place your cursor at the start of
+    line 4.  Press 'ytr', yank-to-(to the character r), which yanks
+    the 'fou' letters (no newline character).  Now press p.  Here is
+    the result: >
+        one
+        two
+        three
+        ffouour
+        five
+        three
+<   This is good, even though the keys 'ytr' has not been mapped
+    to YRYankCount, the YankRing still pasted the most recently
+    yanked text.  Since the text did not have a newline character
+    the 'fou' was inserted after the 'f'.
+
+    Now replace that previous paste with the current element from
+    the YankRing by pressing <C-N>.  This is the result: >
+        one
+        two
+        three
+        four
+        one
+        five
+        three
+<   The #1 entry in the YankRing is still the line "five@".  When
+    choosing the next entry, it wraps around to the last entry in
+    the yankring, element #5.  The 'fou' was replaced with 'one^@'.
+    Since it had a newline character in it (when it was yanked) the
+    newline is included when it is pasted.
+
+                                                 *YRPush-example*
+    Assume you need to paste text from the system clipboard, and this
+    is text you will need routinely.  We can simulate this by running
+    this command (see |quote+|): >
+        :let @+ = "From the clipboard\n"
+        :echo @+
+
+<   With the cursor at the start of the line with the word 'five', press 'p'.
+    We still have pasted the 'fou' which is in the default paste buffer. >

+        Next - "+p
+<   The line changes since we bypassed the yankring, and specified
+    which register to get the text from: >
+        four
+        five
+        From the clipboard
+        three
+<   <C-P> replaces this with the #1 entry in the yankring: >
+        four
+        five
+        five
+        three
+<   Now add the contents of the clipboard to the yankring: >
+        :YRPush '+'
+<   Move the cursor to the last row 'three' and press 'p'.  The result is: >
+        four
+        five
+        one
+        three
+        From the clipboard
+<   YRPush '+' adds the value of the register '+' to the yankring, but it
+    also adds its contents to the default Vim paste buffer.  So pressing
+    'p' pasted this text.  Adding a new value to the YankRing we have
+    repositioned it which you can see with: >
+        :YRShow or F11

+    of the commands available.
+
+    Using the YankRing window can be much faster if you do not want to cycle
+    through the YankRing using <C-P> and <C-N> to find the element.
+
+                                                 *multiple-items-example*
+    There are times when you need to move through a buffer capturing many
+    different lines (or snippets of code) and eventually want to switch
+    buffers and paste these elements.  With some advance planning you can do
+    this without the YankRing by issuing commands of the form: >
+        "ayy
+        "Ayy
+<   When specifying the register using UPPERCASE, Vim appends the yanked text
+    to register "a, instead of replacing it.  Many times you forget the
+    advance planning (or didn't even know about this great feature) you can
+    use the YankRing window to do this easily.  If this is the current
+    yankring: >
+        :YRShow or F11
+            --- YankRing ---

+            4     two^@
+            5     one^@
+<   The YankRing works in |visual-mode|.  To demonstrate move the cursor in
+    the buffer to the line with 'two'.  Press 'F11' to display the yankring
+    window.  Move the cursor to element 2, press 'V' to enable
+    |linewise-visual| mode and then press 'j' twice.  This should have
+    visually highlighted elements 2,3,4.  Press 'p' to paste all the
+    highlighted elements: >
+        one
+        two
+        four
+        three
+        two
+        three
+        four
+        five
+<   You can see here it has pasted four, three, two after the second line of
+    the buffer.  Now press 'u' to undo our last change.  Leave the cursor
+    on the second line 'two'.  Press 'F11' to show the YankRing again.
+    Visually select the same lines, but this time press 'r' instead of 'p'.
+    'r' is for reverse, so it will paste the following: >
+        one
+        two
+        two
+        three
+        four
+        three

+    The same behaviour listed above (by visually selecting items in the
+    YankRing window) can be achieved using the YRGetMultiple command.
+    Assume there are 10 elements in the YankRing. >
+        :YRGetMultiple  4   " Will paste elements 1,2,3,4
+        :YRGetMultiple! 4   " Will paste elements 4,3,2,1

+    The default size of the YankRing is 100 elements.  It can be
+    tedious searching through the YankRing to find the element you
+    need.  YRSearch is similar to YRShow except it will limit the

+    the cursor to inside the buffer (not the YankRing window).
+
+    |characterwise-visual|
+        Go to line 1, press 'v' and move using the cursor keys until you have
+        highlighted some text.  Then press y to yank the visually selected
+        area.  Pressing p with paste the yanked region.
+
+    |linewise-visual|
+        Go to line 2, press 'V' and move using the cursor keys until you have
+        highlighted some text.  Notice the entire line is selected (including
+        the carriage returns).  Then press y to yank the visually selected
+        area.  Pressing p with paste the yanked region.
+
+    |blockwise-visual|
+        Go to line 3 column 4, press CTRL-V and move to the right using the
+        cursor keys until you have highlighted some text.  Then press y to
+        yank the visually selected area.  Pressing p with paste the yanked
+        region.  Notice the pasted text retained its blockwise visual
+        characteristics.

+7. History                                       *yankring-history*
+
+  10.0: January 31, 2010
+         NF: Change the buffer name to [YankRing] to resemble other
+             non-user buffers.
+         NF: Added g:yankring_min_element_length which can prevent
+             items from being added to the YankRing if they are too small.
+             For example, single character deletes (Vedran M).
+         BF: When shifting focus back to Vim, the YankRing may incorrectly
+             report: "YR:Failed to change to the yankring buffer,
+             please contact author".
+         BF: When entering Vim for the first time and hitting "p"
+             nothing was pasted (Mark Huiskes).
+         BF: When entering Vim for the first time and the
+             yankring_clipboard_monitor = 1, the clipboard entry
+             was not automatically added to the yankring.
+         BF: When overriding the default and setting
+             g:yankring_window_use_bottom = 0, the YankRing would
+             report the error (Sergey Khorev):
+                 E21: Cannot make changes, 'modifiable' is off
+
+  9.0: August 29, 2009:
+         BF: You cannot execute a macro with ":normal @a".  It is still
+             not possible, but you can execute it with ":normal! @a"
+             (A S Budden).
+         BF: When g:yankring_persist = 0 the YankRing could go into
+             an infinite loop (A S Budden).
+         BF: When replaying a macro which used any of the zap
+             keys (f,F,t,T,/,?) you were prompted again for the
+             string to match on (Ovidiu C).
+         BF: When checking the clipboard for changes
+             (g:yankring_clipboard_monitor == 1) only add the item
+             if it is not already in the ring.  Previously, the item
+             was moved to the top of the YankRing each time you flipped
+             focus.
+
+  8.0: December 21, 2008:
+         NF: Changed the implementation of YRGetSearch() (David Liang).
+         BF: Under some unknown circumstances, the yankring can fail
+             to change to the correct buffer.  Put in code to double
+             check and abort.
+         BF: Yanking and pasting a line which ends in a backslash
+             resulted in the backslash being replaced by "@@@".
+         BF: When repeating a command (".") which used any of the zap
+             keys (f,F,t,T,/,?) you were prompted again for the
+             string to match on (Vasilii Pascal).
+
+  7.0: November 14, 2008:
+         NF: Added support for the / and ? motions so that y/search is
+             supported (Vasilii Pascal).
+         NF: When the YankRing window is displayed (or updated) an additional
+             check is made against the default register.  If it has changed
+             since the YankRing recorded it, the value will be added to the
+             history.
+         NF: Added support for more motions h, j, k, l, H, M, L, ^, 0, -, +, _.
+             And a pile of g motions g_, g^, gm, g$, gk, gj, gg, ge, gE.
+         NF: The YankRing window will display a message it is operating
+             in a limited mode if not using Vim 7.2 or the correct patch
+             level.
+         BF: Correction to some internal code which could lead to an
+             endless loop (John Beckett).
+         BF: Opening and closing the YankRing window with "set report=0"
+             reported "1 line less" messages (Bill McCarthy).
+         BF: Changed the default value of g:yankring_paste_check_default_buffer
+		     to check if the default paste buffer has changed when pressing
+			 'p'.  For example, if a plugin has changed the default registers
+			 it will be pasted rather than the top item from the YankRing.
+         BF: YRMapsDelete did not remove all the maps created by the YankRing.
+         BF: Under particular circumstances, yanking text with embedded @
+             characters were not properly stored and retrieved from the
+             YankRing (Andrew Long).
+         BF: Changed to use xmaps instead of vmaps so that the maps only work
+             in visual mode and not select mode (David Liang).
+
+  6.1: October 31, 2008:
+         BF: If the g:yankring_history_dir contains spaces (default on
+             Windows) an error was reported.  A simple work around was to
+             let g:yankring_history_dir = 'c:\Vim' or no spaces (Matt).
+
+  6.0: October 25, 2008:
+         NF: The YankRing now maintains the history in a file.  This means
+             if you are running multiple instances of Vim, they all see
+             the same yankring.
+         NF: The location and name of the file is configurable by the user.
+         NF: The g:yankring_separator is no longer used and has been removed.
+         NF: The g:yankring_max_element_length can be used to limit the size
+             of an element in the yankring.
+         NF: The g:yankring_share_between_instances can be used to indicate
+             whether each instance of Vim running on a machine should share
+             the history file or whether each should have their own
+             individual history file.
+         NF: The g:yankring_clipboard_monitor can be used to indicate
+             whether changes to the system clipboard should be added to the
+             YankRing (default is on).
+         NF: The YankRing window can toggle the clipboard monitor by pressing
+             'c'.  See the help in the window by pressing ?.
+         NF: Added some highlighting to the YankRing window (Marty Grenfell).
+
+  5.0: September 21, 2008:
+         NF: The YankRing can recognize certain Vim commands which do not
+             change the contents of a buffer and not attempt to capture it.
+         NF: The global variables which allow you to customize the behaviour
+             are now space separated instead of comma separated.  This
+             provides greater flexibility but will require you to modify
+             your vimrc (if you have customized it). (Andy Wokula)
+         BF: If using <C-O> from within insert mode, the YankRing inserted
+             characters into the buffer instead of capturing the changes,
+             this was fixed by Andy Wokula (Agathoklis Hatzimanikas).
+         BF: The YankRing did not properly account for all the different
+             forms of counts "5yy" worked but "y5y" did not (Edwin Shao).
+
+  4.1: August 9, 2008:
+         NF: The YankRing now allows you to override which operators should
+             be ignored (yankring_ignore_operator).  By default this is
+             set for the standard Vim operators which do not modify any
+             registers (Examples: = and gu) (Andy Wokula).
+         NF: The YankRing did not map v_x (Matt Tolton).
+         BF: The expression register (quote=) was not accounted for correctly
+             (Agathoklis Hatzimanikas).
+         BF: Using the v:operator variable must be escaped when used in
+             a regular expression.
+
+  4.0: June 24, 2008:
+         NF: The YankRing by default now captures all |text-objects| and
+             all motions (|motion.txt|) which Vim supports.  Version 3.0 only
+             supported a subset of the basic motion commands.
+         NF: Prior to this version only predefined maps triggered the
+             capture of data into the yankring.  These maps only supported
+             yanks and deletes.  The YankRing now also supports
+             operator-pending mode, which allows a greater range of operations
+             to be automatically captured and added to the yankring.
+             Operating pending mode functionality requires Vim 7.2 or Vim 7.1
+             with patch #205.  If using Vim 7.1 you can determine this with:
+                echo has("patch205")
+         NF: Prior to this version only yanks and deletes were registered
+             in the yankring.  Changes are now also captured into the
+             yankring.
+         NF: The YankRing will also capture the system cliboard when focus is
+             returned to the vim window.  This is useful if you copy text
+             between applications.
+         NF: The YankRing window always opened bottom horizontal.  Now it
+             can be opened top or bottom and horizontal or vertically.
+             This can be controlled via variables in your .vimrc.
+         BF: The YankRing has an option to persist between instances
+             of Vim by storing the values in global variables within
+             the viminfo.  This has led to some unusual ordering of
+             items in the ring from conflicts between instances.
+             This option has been turn off by default.
+         BF: Their was an issue with yanking using y$.
+
+  3.1: September 10, 2007:
+         NF: YRClear will now unlet all global variables it uses to store
+             the data if the persist storage is specified (the default).
+             Large values in the viminfo file could possibly affect other
+             applications.
+
+  3.0: September 7, 2007:
+         NF: Converted the YankRing to use the new Vim7's List object which
+             means it is no longer compatible with Vim6.
+         NF: By default the YankRing will now maintain the yankring's items
+             persistently by default.  It does this via the |viminfo| file.
+             This means the contents of the YankRing rely on the internal
+             variables of only 1 Vim instance.
+         BF: YRToggle was not unmapping 'gp' and 'gP'.
+         BF: YRSearch prompted the user for a regex even if one was provided
+             on the command line.
+         BF: If g:yankring_manage_numbered_reg is enabled, the "." operator
+             did not correctly repeat the previous action (Pedro DeRose).
+
+  2.2: November 1, 2005:
+         NF: Added 'x' to the list of yankring_n_keys.  This is very useful
+             in visual mode since it can delete a lot of characters.
+
+  2.2: October 19, 2005:
+         BF: If you pressed '?' to toggle the display of the help in the
+             YankRing window, the window would close.  This also applied to
+             'a', which allowed you to toggle the autoclose feature.
+
+  2.1: October 11, 2005:
+         NF: Added the ability for the YankRing to override Vim's numbered
+             registers.  Instead of the numbered registers holding the last
+             yanked value, and the 9 previous deletes, they will now reflect
+             the top 10 items in the yankring.  This allows you to reference
+             them directly with "5p.
+
+  2.0: August 20, 2005:
+         NF: Much improved usability, the YankRing now has a "GUI" to service
+             the yankring.  If YRShow or YRSearch is used, a split buffer is
+             opened which displays all the elements in the yankring.  There
+             are a number of maps that allow you to interact with the
+             contents.  The window can be positioned vertically or
+             horizontally as well as being sized all through options
+             specified in your vimrc.
+	     NF: YRPop can now delete any items from the yankring, rather
+		     that just from the top.
+	     NF: YRSetTop has been removed, it is no longer required as the
+		     internal representation of the YankRing has changed.
+	     BF: If g:yankring_ignore_duplicate is set (which is the default)
+		     you could get some unpredicable results when moving
+			 backwards and forwards (<C-P> and <C-N>) through the
+			 previous values.
+
+  1.7: June 10, 2005:
+         BF: The expression register support added in version 1.6 used
+             getreg('='), which has the side effect of executing the
+             expression register.  Depending on what was in the register
+             this could have unusual results.  Changed to use histget().
+
+  1.6: April 20, 2005:
+         NF: YRSearch is similar to YRGetElem.  Given a regular expression
+             it will interactively display all the elements in the yankring
+             that match the regular expression.  You can enter the number
+             of the element to paste it.  If you have many elements within
+             the yankring, this can help you identify them more easily.
+         NF: Updated the default history size from 30 to 100, which is
+             partially the reason for the YRSearch command.
+         NF: By default it supports "gp" and "gP", in addition to "p" and "P".
+         NF: Added support for the expression register (:h quote=).  Here
+             is an example of how it is used:
+                "="X"<CR>P
+
+  1.5: March 30, 2005:
+         NF: The YankRing now respects the cpoptions setting, if 'y' is
+             included and you press '.', the previous yank command is executed
+             and added to the yankring.  You can also add this behaviour by
+             setting this in your |vimrc|: >
+                let g:yankring_dot_repeat_yank = 1
+<        NF: Duplicates will not be added to the YankRing by default.  If
+             a duplicate is found, the element will be moved to the top
+             of the yankring.  This can be controlled by setting this in
+             your |vimrc|: >
+                let g:yankring_ignore_duplicate = 0 (1 is default)
+<        BF: Regression from version 1.4, the '.' operator may incorrectly
+             insert garbage.
+
+  1.4: March 28, 2005:
+         NF: YRToggle has been updated.  If you toggle the YankRing off
+             (disable) the maps it creates are removed.  Calling YRToggle
+             again will recreate the maps.  This truly disables the yankring,
+             where the previous version attempted to do this via code.
+         BF: Using the '.' operator was not correctly replaying operations
+             that did not move text in some way (g~t_) changed the case
+             of the text but a '.' did not replay it.
+         BF: When replacing previously pasted text the YankRing did not
+             respect what key was used to paste the text originally.
+             All replaced items were pasted using 'p', even if you had
+             originally pasted the text with 'P'.
+
+  1.3: March 16, 2005:
+         BF: The '.' operator did not handle the <<, >> shift operator.
+             Pressing '.' would result in the previous YankRing operation
+             instead of repeating the shift.
+
+  1.2: March 14, 2005:
+         NF: Added support for '.' operator to repeat the last change.
+         NF: Changed YRGetElem to show the contents of the yankring
+             and allow you to choose which element you want pasted.
+             It is only interactive if you do not provide a parameter.
+         NF: Added 'ygg,dgg' default maps by extending the yankring_n_keys
+             variable.
+
+  1.1: March 09, 2005:
+         NF: Added support for the black hole register |quote_|.
+         NF: Custom Maps allows the user to more finely tune the yankring
+             maps to perform whatever action they require.  This function,
+             YRRunAfterMaps(), is run automatically after the YankRing
+             creates it's default mappings.  See |yankring-custom-maps|.
+         NF: Added some more default maps by extending the yankring_n_keys
+             variable.  It now contains:
+                yy,dd,yw,dw,ye,de,yE,dE,yiw,diw,yaw,daw,y$,d$,Y,D,yG,dG
+             NOTE:  You can easily extend these default mappings by
+             creating this global variable in your |vimrc|, you do not
+             have to wait for the plugin to be updated.
+         NF: Added support for Dr. Chips GetLatestVimScripts plugin.
+         BF: The check for g:yankring_n_keys was incorrect, so it was not
+             possible to override the default maps.
+
+  1.0: March 08, 2005:
+         NF: Initial release.
