Most people don't know how to use tabs properly. But tabs can be really powerful, especially if you are building a form or table of contents.
Below you see a simple form with the tab ruler above it. Select each tab and type an underscore in the "Leader" box. Whatever character you type in the "Leader" box will repeat all the way to the tab. The underscore becomes the lines on the form. Much quicker and more accurate than trying to draw the underlines yourself. And much, much easier to edit the form later.
If you are building a table of contents, you may want to have a dotted line from the end of the chapter name to the page number. Don't type a bunch of periods! Just set the "Leader" to a period. You can also use a right-justified tab to line up all your numbers correctly. Faster to build. Faster to edit.
