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