I've since returned to playing PS2, however I use my Right Click button as my Forward Keybind. I'm unable to determine what the Right Click Revive Default keybind is so I can reassign it.
By default right-click is 'ADS zoom' on the infantry tab or something similar. Alternatively, you could always reset back to default wholesale and redo the ones you need.
Thanks guys. I may have to do a reset simply to see what the actual name is, however I think ADS Zoom is the default. Its curious how they map the keybinds in PS2 particularly the inability to have a Primary to Secondary, back to Primary keybind that's exclusive for just that command. I appreciate the feedback.
