Note that in vanilla Emacs C-x z repeats the last command; C-x z z z... 
repeats it again and again.  It displays a message in the echo area 
"Repeating command <name of last command>".

You can also for example (global-set-key (kbd "C-z") 'repeat) to repeat 
any command with a single keystroke, in which case you can also change the 
prefix argument while repeating the command: C-x o C-z C-z C-- C-z 
executes (other-window 1) three times, then (other-window -1).
