Camera Previous keyboard

Hi. Im trying to tame my Spacemouse. Id like to assign/macro one of the buttons to the previous zoom - ie camera previous. Zoom Extents worked fine for the other buttons. Ive done it once before somehow but cant remember.
Thanks for any suggestions.

Have you tried assigning a keyboard shortcut to Camera/Previous? Then you should be able to assign a button on the Space Mouse to that keystroke. I assigned F5 as the keystroke.
