Standard external keys provided by Windows Phone 8.0 are Volume down, Volume up, Power and Camera. Is there anyone have the list of external key press shortcuts (like soft reset)?

(WP7.5/WP8) Power + Start Button
(WP8.1) Power + Volume Up
Screenshot is now Volume up + power. Hard Reset is Volume Down + Power + Camera
