When you have a checkbox in a column on a data entry page, you can quickly select all or deselect all and have FAST updated the checkbox for you! On a data entry page that uses a checkbox, right click the column title. A popup box is displayed. Scroll down until you see the 'Select All' and 'Deselect All'. As soon as you choose one or the other, the column is updated. Make sure you save to finalize the change. Keep in mind that if you have filtered the results, only those filtered rows will be updated.
