Gundo.vim is Vim plugin to visualize your Vim undo tree.
Current status: Alpha. It will probably eat your data. Be careful.
==================================================================
Requirements
------------
* Vim 7.3+
* Python support for Vim.
Installation
------------
Use [Pathogen][]. Don't use pathogen? Start.
Add a mapping to your `~/.vimrc` (change the key to suit your taste):
nnoremap <F5> :GundoToggle<CR>
[Pathogen]: http://www.vim.org/scripts/script.php?script_id=2332
Usage
-----
When you're editing a file you can bring up the undo graph for that file with
`<F5>` (or whatever key you mapped it to).
Press `<F5>` again to close the undo graph and return to your file.
Use `j` and `k` to move up and down the graph. The preview pane will update with
a diff of the change made by the undo state you're currently on.
Press return to revert the file's contents to that undo state and return to the
file.
