Hi there.
Just reporting an issue with non default keyboard configs.

The default F=(Use/Grab Item) key, does not unbind.

Example :

F=Move right
Lctrl= Use/Grab

This results in F key dropping any items held, As well as triggering "visor hack" when available.

Any way to tweak/fix this?

I believe Warhead had a similar issue with Dual Pistols, Which was corrected with a cfg tweak.
