Notes

• This function doesn't return a value while a MessageBox is being displayed, presumably because input is switched over to the MessageBox.
• Bear in mind that this function returns 1 for as long as the key is held down, so it's generally a good idea to trap the key and then wait until it is released, i.e.:

if ( curKey && isKeyPressed curkey ) ; key still being held down
  return ; wait until it's released
else
  set curkey to 0
endif

if ( isKeyPressed <keyCode> )
  ; do stuff
  set curKey to <keyCode>
endif
