i don't use MCE Remote. I'm using IMON where i've set up a specific keyboard key or shortcut.
Maybe I can help for IMON-users:
I did it this way:
1. In MP Plugin configuration I chose Action_Type "ACTION_TOGGLE_MUSIC_GAP" wich I don't need at all. This Function is normally mapped to Keyboard "G" inside MP.
2. In IMON Manager I now defined a function called "SleepTimer", using Keybord "G" and mapped it to the "Timer"-key on my remote. Works perfect and has even the right keyname on the remote control
BTW: Great plugin!
