I had to retire my Roccat Nyth for it's right click failing on me and to replace it I got a Logitech G600 mouse recommended to me by one of my friends. I have looked through the menus and tried googling for an answer but cannot see to find a button that correlates to mouse button 4 and 5 onto my buttons that I commonly use for like a melee attack or throw a grenade. I have a work around for it in the form of a macro but for some games like Destiny 2, to activate a special effect requires holding down the button which the macro I have only treats it as a button pressed down and button released. Where in these menus can I find mouse/thumb button 4 and 5 so I can have full efficiency back for my new mouse?
