  23      NAMING RULES FOR USER-COMMANDS
  24      Here's the set of rules to apply when a new command name is introduced:
  25
  26      1) Use the object.event order. That is, use `word-forward'
  27         instead of `forward-word'.
  28      2) Don't introduce an alias for an already named object. Same for events.
  29      3) Forward movement or focus is called `forward' (not `right').
  30      4) Backward movement or focus is called `backward' (not `left').
  31      5) Upward movement of focus is called `up'.
  32      6) Downward movement is called `down'.
  33      7) The begin of an object is called `begin' (not `start').
  34      8) The end of an object is called `end'.
