I've had this problem, but i don't have the "save to mouse" option, please help! Image: https://gyazo.com/7eaa37c17eef97cd0466294b7d028e38 Also, how do i make a thread?

Can you map the mouse buttons (eg the forward button) to a key on the keyboard? (especially numbers or the space key) That would be amazing. Thanks in advance for the help!
