Hi, I need to teach my MX-3000 the IR code for CTRL+ALT+R on an HTPC to start a certain software program. However, when I try to teach, pressing any of the keys alone will register a good IR code, and I'm unable to hit all three at once. I though that the ALT and CTRL buttons simply changed the output of the regular key being pressed (in this instance "R"), but it seems they are individual key presses in their own right.

How do I go about learning the triple key press?

Thanks
Chris
