LMT settings topic

Hi everybody, I need your help! I'm looking for a way to set a "power menu" button in LMT. There is no default option to choose (I'm currently on Archidroid 3.0.1.1), so I was wondering if there was a terminal command (or key or script) to do that. Does someone know the activity path of Power menu, too! It could be another solution.

Hope to get myself explained, thank you guys
