vip: Repeating and Undoing Modifications

 
 2.9.5 Repeating and Undoing Modifications
 -----------------------------------------
 
 VIP records the previous modifying command, so that it is easy to repeat
 it.  It is also very easy to undo changes made by modifying commands.
 
 ‘u’
      Undo the last change.  You can undo more by repeating undo by the
      repeat command ‘.’.  For example, you can undo 5 previous changes
      by typing ‘u....’.  If you type ‘uu’, then the second ‘u’ undoes
      the first undo command (‘vip-undo’).
 ‘.’
      Repeat the last modifying command.  Given count N it becomes the
      new count for the repeated command.  Otherwise, the count for the
      last modifying command is used again (‘vip-repeat’).
