Secondary button setting?

Hey guys, I’m in need of some help.

I play gmod on a mac and I cant really use the physics gun because the crappy mac mouse only has one button so i cant click the right and left at the same time. Is there a way I can set my secondary fire as both right click and something else? So i can use two buttons for the same command?

Just buy new mouse. Most will work with mac anyways.

yeah but im lazy and i dont wanna go to the store

i find out how to do it but i need to know the command for secondary fire in the console

inb4 buy me one

What he Said, the Concmd is +attack2
