Tabs position text at specific horizontal locations in a frame. The default tab settings depend on the Horizontal ruler units setting in the Units & Increments preferences dialog box.
Tabs apply to an entire paragraph. The first tab you set deletes all default tab stops to its left. Subsequent tabs delete all default tabs between the tabs you set. You can set left, center, right, and decimal or special-character tabs.
You set tabs using the Tabs dialog box.
