Direct entry of video Zoom and Vertical Shift etc (able to be keymapped)

Hi, it would be great if we could map a key to directly set the video player Zoom and Vertical Shift values and possibly other settings to a direct value during playback. This would be super useful to those of us using constant height / cinemascope screens, but probably others would find some use for it as well. For example, I would like to have a remote key mapped to, say, “Zoom = .74” or whatever, to immediately scale 16:9 content to fit within the confines of my 2.4:1 screen.
