allow noninteractive directional focus.

make keybinds noninteractive when the last key in the chain has no modifiers (i think this is what the code was supposed to do but failed.)

don't reset key chains during an interactive action. reset them after an interactive action finishes (honoring chroot)
so you can <C-t><C-Up>Stuff<//> and it'll do stuff as you hit C-Up, you dont have to keep hitting C-t
