For multi-button mice each button can be assigned an invidual action (select, rotate model etc.). For those who use single-button rats, this toolbar changes the function of the first (or left) button between select / interact, rotate model, and translate model. Selecting these buttons overwrite the stored action for the left button in the Preferences.
