I am just not convinced that an O(n) visual scan over the keyboard is that useful. What programs really need is a good "search" function for commands. Obviously scanning over an entire toolbar is useless, but if you can search named commands and the application shows you where in the menu the command is and what its shortcut is, then that would be better than a keyboard that just puts toolbar icons on the keys.

(I have used variants of this feature in many applications and love it. There are a bunch of functions in Fusion 360 whose name I know, but not where in the menus it is. But they have a search-and-invoke UI, so I can run them. I do wish it would show me where in the menus they are, though, because after the first couple times it sure is inefficient.)
