Suggestion: allow me to collapse a menu by hitting the left arrow key even if I'm not on the row with the expansion arrow. If I'm adding a component to a schematic, I use the arrow keys to go up/down in the component list. I can use right arrow to expand a menu, then I'll scroll down a bit to find a component. If I don't find my component, I either have to keep scrolling down until I can move onto the next list, or I have to scroll all the way back up to the expansion arrow, only then can I hit the left arrow key to collapse the menu.
If I could use the left arrow key no matter what row I was in, I expect it to collapse the deepest menu that I'm inside of. This will save a bunch of time for keyboard users that scroll through a ton of items. I see no immediate drawbacks to this. If you're in multiple submenus, then each left arrow key simply collapses the deepest one one at a time. Happy to explain further or take screenshots if it will help.
Thanks!
