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.
