-Run `:help gundo` for the full docs. Here's the in-a-nutshell version.
-
-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.
