[To Developers of HB] Sending "modified" keystrokes to WoW?

[strix]

Is there some quick way to send Alt+Key into WoW window?
Lets say for 0 key.

Just 0 key would be:
KeyboardManager.KeyUpDown('0');

How to add Alt+0 into it?

My friend developed that:

{
KeyboardManager.SendMessage (0x0100, 0x30, 0x20); // (Press, 0, with Alt)
KeyboardManager.SendMessage (0x0101, 0x30, 0x20); // (Release, 0, with Alt)
}

Will it work?
