As discussed on irc, KEY_MEDIA seems like the best answer. There's something in the mce keymap already mapped to KEY_MEDIA, but I don't seem to have that key on either of the mce remotes I have handy at the moment, so its probably on one of the less common remotes... We can change that key's mapping at a later date, if someone wants to use that button for something different than the green button. -- Jarod Wilson jarod@xxxxxxxxxxxx -- To unsubscribe from this list: send the line "unsubscribe linux-media" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
