On(keyPress)....on(keyup)?

Hello all, this shouldnt be too hard… but i couldnt do it…

I have a movie clip call ‘bob’. When I press the ‘a’ key on the computer keyboard I want ‘bob’ to gotoAndStop at frame 5. Then when I release the ‘a’ key I want movie clip ‘bob’ to gotoAndStop at frame 1.

The problem is that unlike when using the pair on(press) on(release) for the mouse, on (keyPress “a”) doesn’t have a on (keyup) handler for the keyboard buttons as far as I can tell.

You help is very much appreciated.
Cheers, R

on (keyPress “a”) {
_root.bob.gotoAndStop(5);
}
on (??? “a”) {
_root.bob.gotoAndStop(1);
}
