All text boxes : The opposite of ctrl+v (like in emacs) I like using ctrl + v on mac for jumping with the cursor to the next screen - something like page down but the cursor moves too.

Do you know any way to do the opposite - jumping to the previous screen - like page up but also with the cursor moving?

I'd love a universal solution - i.e. working in all text boxes.

UPDATE: I've refreshed my mind that there's a key binding in terminals that does exactly what I want and that's meta + v but that doesn't work in all Cocoa text boxes as ctrl + v does.
The Emacs command for page up is Meta-v.  Unfortunately, Cocoa only seems to implement the Control-key commands, not commands with Meta.  (Alt is used for special or international characters.  Alt-v gives me a square root key on my keyboard layout.)
