Keyboard quick keys show show sub-menu on tap begin, and buttons on tap ended.

I think it would feel a lot smoother if the keyboard quick keys, such as the one that pops up “[]{}-+*/…” should appear on tap begin so we can just drag our finger to the item we want and release, this means we can select an item without lifting our finger off the screen.

I completely agree, @ljdp. I haven’t yet had a chance to work on something like this, but it’s on my mind.
