Item rotation

I set up Gmod so that I could use my Xbox 360 controller with it. However, now the rotation with gravity gun (or whatever it’s called) doesn’t seem to work. The control to move it closer and further from you does though. I looked through the control settings and couldn’t find one meant for that. Anyone know which setting needs to be changed to fix this?

It’s called the Physgun. And with the keyboard, you need to hold down your USE key to rotate a prop in midair. You forgot to bind your use key to some button on the Xbox controller?
