An idea I read about long ago is ring-based context menus. So instead of getting a square list of choices, one per line, you get each choice arranged in a ring around your cursor. So maybe Copy is at 1 o'clock, Cut 2 o'clock, etc. It would be easier to "target" your choice, and even easier once you learned the position of things. I don't know if this has ever been tried. Maybe in a game? EDIT: apparently this is called a pie menu or radial menu: https://en.wikipedia.org/wiki/Pie_menu
I seem to remember trying at least one X11 window manager that used pie menus back in the early 90s - but unless the apps have small menus with small labels, you just get chaos.
