I would like to assign the "track navigation tool" to left mouse button plus right mouse button. instead of the default middle mouse button plus alt (due to my middle mouse being broken). however in the hot keys options there is no option to assign and mouse clicks to hot keys. Any help with this would be much appreciated as i have been trying to fix this for a while.

P.S.

Telling me to get a new mouse or different mouse is not the answer I am looking for.
