Logitech G502 mouse buttons

[WesleyT2]

I have the logitech g502 mouse and I want to assign the side buttons to do commands like mouse 4 but how do I find them in the logitech gaming software?

open the software, click on the arrow on the right side (next to the pic of your mouse),
it will bring up the detailed settings for wheel/all buttons.

move the pointer/highlight the button to change, and select what you want it to do.
some games might override that tho.
