I was wondering how to exit MediaPortal by pushing a single button on the Logitech Harmony One? I got Harmony One to start by a single button by assigning it using LM Remote Keymap. But I don't see any clear ways to exit MP, aside from Alt-F4. I don't know how to assign this to LM Remote keymap. I also fear that doing Alt-F4 would damage the application after some time. Please help.
