This guide shows you how to bind the thumb mouse buttons on your mouse if you are unable to in-game.
How to Binding Thumb Mouse Buttons
- Go to:
- Open GameUserSettings.ini with any text editor
- Find any ActionKeyMapping that you want to change.
In my case I wanted to “Stab” and “Overhead” with my thumb mouse buttons. On that ActionKeyMapping change the Key= value to whichever input you want, in my case ThumbMouseButton2 which is the back button on the side of the mouse (see image below, AttackU). Now you will strike from above with your back button. I then did the same on AttackD for ThumbMouseButton so that I stab with the forward button on my mouse.
- Do any more changes you want and then save the file, it should now work in-game.
A list of all keys can be found here.
After it should be showing up as correctly bound in-game.
