What Is The Ruler At The Top Of The Text Box?

The ruler at the top of the text box is used both as a measurement tool for the text box itself and as a way to set tabs.







To set a tab, simply click in the ruler on the desired measurement where you’d like a tab. You will then see a black L mark that indicates where the tab is. From then on, when you press the Tab key on your keyboard while in that text box, the cursor will immediately move over to that line.
