     NAMING RULES FOR USER-COMMANDS
     Here's the set of rules to apply when a new command name is introduced:

     1) Use the object.event order. That is, use `word-forward'
	instead of `forward-word'.
     2) Don't introduce an alias for an already named object. Same for events.
     3) Forward movement or focus is called `forward' (not `right').
     4) Backward movement or focus is called `backward' (not `left').
     5) Upward movement of focus is called `up'.
     6) Downward movement is called `down'.
     7) The begin of an object is called `begin' (not `start').
     8) The end of an object is called `end'.
