Turn off LCD when recording when press unlock button just to save power when u want take long shot and forget to set power save settings.
so i will finally use that neverused button :))) i like the idea (but think it's not a omnipresent button, some cameras did'nt have it i think). anyway it's a good idea and could be a feature for who has that button
I'd go for DISP/INFO, but with an option (disabled by default) in the powersave submenu.
Unlock can only be detected in playback mode, where it already has a purpose ;)
Nice. As long not going thru the whole disp info list.
