Should I rebind my Lean?

I used to use footswitches to lean, when that broke I went back to using Q and E. I press both keys with one finger and lift up the bottom or top of the finger if I want to stop moving or leaning.

I am using a Deathadder V3 Pro and I was wondering if I should rebind to the mouse buttons.

If you are curious I use shift for slow walk (toggle), space to jump, alt to sprint, and ctrl to crouch. (Control Mwheel down is to toggle sights and mwheel up is damage ability, mbutton back is for another ability. Mbutton forward is for laser/flashlight
