To undo recent changes, from normal mode use the undo command:
u: undo last change (can be repeated to undo preceding commands)
Ctrl-R: Redo changes which were undone (undo the undos). Compare to
.to repeat a previous change, at the current cursor position. Ctrl-R (hold down Ctrl and press
r) will redo a previously undone change, wherever the change occurred.
A related command is:
U: return the last line which was modified to its original state (reverse all changes in last modified line)
U is not actually a true "undo" command as it does not actually navigate undo history like
CTRL-R. This means that (somewhat confusingly)
U is itself undo-able with
u; it creates a new change to reverse previous changes.
U is seldom useful in practice, but is often accidentally pressed instead of
u, so it is good to know about.
Note that unlike most programs which maintain a linear undo history, Vim maintains an undo tree containing every edit made to a buffer. To learn how to use Vim's undo tree, see the separate article on using undo branches.
- Recover from accidental Ctrl-U, which explains what constitutes a change which can be undone.
- Using undo branches, which explains Vim's unique and very powerful undo tree.
