Removing the right click window.

[CanSarac 0]

Hello simmers, 

I started to be bugged by the annoying right click, it has very low uses for me and I would like to remove or more preferably assign it to a keyboard button. is it possible?

I use chaseplane and my mouse wheel acts like a trim wheel when app or dep; so I need to assign a new heading or alt or anything else with mouse clicks but this window keeps appearing and annoying me.
Any solutions for this?   

Thanks,
