      res[1].replaceText(res[1].text.length-1,res[1].text.length,'');
    break;
    }

Answer 1

Don't use Buttons, use MovieClip instances (different states on different frames) instead. That gives some more work to do since you'll have to switch states manually, but gives more flexibility.

Here's an example with 3 different states (normal, hover, click): http://pastie.org/1276725

As you can see, it has public methods to trigger all states. The mouse-events are triggered automatically, but you can use these public methods to change states externally (eg. from keyboard input).

Answer 2

Well, the keyboard doesn't exactly have a "rollover" since it's not a mouse. But you can use the keydown event to change the image to the rollover image, and the keyup event to change it back to the normal image. Then put your code (which you pasted in the question) into either keyup or keypress. This should make the behavior you're looking for.

By the way, what happens when you press backspace before entering any numbers? I suspect a JavaScript error will occur; look at your case 8.

Answer 3

Depending on the language, you could do this:

switch (Event.keyCode)
{
  case (int)'0':
    myButton0.click();
    res[1].appendText("0");
  break;
  ...
}

It's hard to answer specifics if you don't provide a language.

[Edit]

I don't know anything about actions script3 sorry. Some languages allow you to set the depressed button status.

myButton.setDepressed = true;
wait(100);
myButton.setDepressed = false;
