Hotkey for Occlude Background Geometry?

Hotkey for Occlude Background Geometry? Does it exist? I use this button about twice every minute and I’m getting tired of hitting that toggle over and over.

Don’t think so. The logical one would be CTRL-TAB-4, but I think the devs have overlooked this.

Yeah I could really use a hot key for occlude in the next blender. maybe they’ll put one in.
