+** New mode 'repeat-mode' to allow shorter key sequences.
 Type 'M-x repeat-mode RET' to enable this mode.  You can then type
 'C-x u u' instead of 'C-x u C-x u' to undo many changes, 'C-x o o'
 instead of 'C-x o C-x o' to switch windows, 'C-x { { } } ^ ^ v v' to
 resize the selected window interactively, 'M-g n n p p' to navigate
-next-error matches.  Any other key exits repeat mode and then is
-executed normally.  'repeat-exit-key' defines an additional key to
-exit mode like 'isearch-exit' ('RET').  The user option
-'repeat-exit-timeout' specifies the number of seconds of idle time to
-break the repetition chain automatically.  With 'repeat-keep-prefix'
-you can keep the prefix arg of the previous command.  For example,
-this can help to reverse the window navigation direction with
-e.g. 'C-x o M-- o o'.  Also it can help to set a new step with
-e.g. 'C-x { C-5 { { {', which will set the window resizing step to 5
-columns.
