Can't use Ctrl or Alt keys?

Tried assigning ctrl+1,2,3,4 etc for STO in-game use, and i'm using Alt+1 for switching between windows.


Trying to get ctrl+1 to work in-game in StarTrek Online isn't working, but if i want to use Ctrl+1 for switching to screen 1 it works fine (but i have screen switching on Alt keys so that doesn't matter).


Any idea what's up? Is there some known config issue?

Try enabling the Hold option on the Mapped Keys in question.
