  31 KEY BUTTONS
  32
  33 Continuous button event tracking is complicated by the fact that two different
  34 input sources (say, mouse button 1 and the control key) can both press the
  35 same button, but the button should only be released when both of the
  36 pressing key have been released.
  37
  38 When a key event issues a button command (+forward, +attack, etc), it appends
  39 its key number as a parameter to the command so it can be matched up with
  40 the release.
  41
  42 state bit 0 is the current state of the key
  43 state bit 1 is edge triggered on the up to down transition
  44 state bit 2 is edge triggered on the down to up transition
