" "Uppercase word" mapping.
"
" This mapping allows you to press <c-u> in insert mode to convert the current
" word to uppercase.  It's handy when you're writing names of constants and
" don't want to use Capslock.
"
" To use it you type the name of the constant in lowercase.  While your
" cursor is at the end of the word, press <c-u> to uppercase it, and then
" continue happily on your way:
"
"                            cursor
"                            v

"                            cursor
"
" It works by exiting out of insert mode, recording the current cursor location
" in the z mark, using gUiw to uppercase inside the current word, moving back to
" the z mark, and entering insert mode again.
"
" Note that this will overwrite the contents of the z mark.  I never use it, but
" if you do you'll probably want to use another mark.
