Hi there, I’ve recently learned about the mouse system and I was wondering is there a way to switch Right-Click Mouse Button and Left-Click Mouse Button? I tried looking at the keys and couldn’t find any specific key.
THANKS! 
Anyone who tried this? UP!
help anyone? 
I’m not sure what you’re asking is possible.
This guy was successful in changing keybinds for the gamepad that aren’t listed in the game settings by using a program that edits the xml files:
However, I looked into that reddit post and some people there were asking about the exact thing you are as well as editing the mouse buttons in general. Some people there state it isn’t possible because they aren’t listed in the xml files
This is a direct link to the reddit post instead of going to the thread above first (question and answer is near the bottom):
Nope, just the keyboard buttons.
