Please Help!

How do you rebind/remap xmousebutton2 to a keyboard key? My mouse only has 3 buttons, not 5, Thanks in advance.

For example, if I click ALT, it clicks mouse button 5/xbutton2

What keyboard do you have? Mouse? If you have a razor keyboard/mouse you should be able to download the software for it. Razer Synapse. Remap through there.

THANK YOU SO MUCH
