    Really? Isn't KEY_HOME the home key on a standard keyboard?

    I'm still not sure what key codes are best either. I've implemented this
    approach, and I went with BTN_TASK and KEY_PROG2, but I'm getting the
    idea that BTN_TASK was intended for a mouse button so I'm not really
    sure if it's a good choice or not. I'll follow up with the patches.

    Thanks for the feedback so far.
