I'd like something physical I can feel and use muscle memory to remember. Having to search the screen, interpret some obscure glyph and make sure I touch the right spot requires far too much attention for most tasks. Volume down + left swipe to save a file. Camera button + screen tap to go to the app's home screen. Something like that, so I don't have to look. I'm not entirely familiar with screen gestures, but I guess that's the closest analog, so long as they aren't too complicated or picky.
