I buyed a mouse yesterday with 5 buttons with the idea to use the extra buttons on the mouse in L2
So normaly in windows options u cant configure ur extra mouse buttons and u need extra software.
Here is one good that i use :

After u install that very cute program u will see something like that:
So if u want to make one of ur mouse buttons to simmulate a button from ur keyboard u must do this :
And watch the specifics when u define a key. For example if u want to simulate with the 5th button on ur mouse, F7 u shold make it {F7} with the F and 5 letter from ur keyboard.
Also to identify witch key u are configurateing u can press that key and u will see how it will light up on the program.
