TL;DR: Are we not able to use shift or ctrl as modifiers for keys?
Example: hide chat command by default is ctrl+shift+c. If you press this combination character crouches (ctrl) and uses ability 1 (shift) and closes the chat. I also tried to put this combination into my macro key so it would be only one key press but that didn’t help.
I’m trying to put push-to-talk to my macro keys on keyboard (Logitech G510s). I try to keep macro keys as obscure as possible to not interfere by accident with any program so I have set P-T-T into ctrl+alt+Num3 and Overwatch options->controls accepts this keybind (shows it correctly, with shift as modifier I only got shift to show as keybind). However when the macro key is pressed it crouches the character and this of course is not desireable.
