Pressing the % (or press Alt-D) button displays the default discount rate which is immediately applied to the totals. The button on the right allows you to select another discount rate from the drop-down list, or, you can type in the rate if none of the pre-sets are suitable.
Pressing the % (or press Alt-D) for the second time erases the discount calculations.
The discount rate may be set under Options/General. Note that the discount rate will always revert to the default after the job has been cleared.
