i think i've figured out the source of a problem i've been having, i just don't know how to solve it (or report it).

i have two macs and an ipad. i try to use Universal Control. it mostly works. but.

if i have a mechanical keyboard or a small macropad keyboard attached (non-apple keyboard), or a gaming mouse (which has a keyboard device to it, so you can program buttons to keystrokes), then on the remotely-controlled machines, modifier keys don't work. shift/cmd/alt/ctrl. it's ... maddening.
