In Word 2013 indents and tabs add structure to documents. Use the MS Word indent ruler and tabs to help make documents clearer.
Using tabs gives you more control over the placement of text. By default, every time you press the Tab key, the insertion point will move 1/2 inch to the right. Adding tab stops to the Ruler allows you to change the size of the tabs, and Word even allows you to apply more than one tab stop to a single line. For example, on a resume you could left align the beginning of a line and right align the end of the line by adding a Right Tab.
Pressing the Tab key can either add a tab or create a first-line indent, depending on where the insertion point is. Generally, if the insertion point is at the beginning of an existing paragraph, it will create a first-line indent; otherwise, it will create a tab.
The tab selector is located above the vertical ruler on the left. Hover the mouse over the tab selector to see the name of the active tab stop.
Although Bar Tab, First Line Indent, and Hanging Indent appear on the tab selector, they're not technically tabs.
It's a good idea to remove any tab stops you aren't using so they don't get in the way. To remove a tab stop, click and drag it off of the Ruler.
Word can display hidden formatting symbols such as the spacebar (), paragraph (), and Tab key () markings to help you see the formatting in your document. To show hidden formatting symbols, select the Home tab, then click the Show/Hide command.
