Things I didn’t test are the other modes in 3dview: sculpting, grease pencil, weight painting, etc. You probably could just open the .py file in Vim (or any other less powerful editor 
) and search for all occurrances of RIGHTMOUSE - you can also use the search menu in the Input keymap editor of course (set to keybinding, then enter right mouse for all cases that are bound to RMB).
