Forums Scripts & Popups Sending keystrokes to a process or program

I'd like to remotely send keystrokes to processes on other computers via mIRC.

So, say I've got 3 computers sitting side-by-side, and they've all got mIRC clients running. I want to be able to, in a private room, issue a command like !Attack, and they'll all send keystrokes to process X, which I identify.
