Keyboard shortcuts

With the command editor I used to be able to search for any command and assign any shortcut I like to it. But the new keyboard shortcut settings dialog seems very limited, I can’t chose a simple shortcut like alt+anything, and I can’t search for commands. Am I missing something?

I’ve been trying out Rhino 8 wip for a few days now, still not able to find the way to make a shortcuts!
We must be missing something.
