I wanted to rearrange the skills in the skill tray for ground combat and I removed the primary and alt fire skills from it, believing they were already set on the mouse buttons. But they are not, only the location they were on in the skill tray was linked to the mouse. And now I can't figure out how to put them back in. Primary and alt fire for the ground weapons are considered skills so there isn't an option to bind them in the options menus.
How do I reactivate them? I tried swapping weapons, it didn't work.
Edit:OK. Found them. The skill tray has a button that shows all available skills. They are in that list. The name given to the primary and alt fire skills may differ depending on the weapons you have equipped.
