| − | <code>Ctrl-R</code> means to hold down the <code>Ctrl</code> key then press the <code>R</code> key. Note that you do not press the <code>Shift</code> key. Vim documentation uses traditional computer terminology including CTRL-R. In keeping with a more modern approach, we generally use "Ctrl" rather than "CTRL" on this wiki. The tips are not entirely consistent regarding whether to write Ctrl-R or Ctrl-r, but mostly Ctrl-R is preferred. [[User:JohnBeckett|JohnBeckett]] 10:04, March 18, 2010 (UTC) |

To undo recent changes, 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 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 u and 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.
