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