Microsoft Office applications include several different toolbars, many with tools you have never or will never use. There are likely some tools on your visible toolbars that you have never and will never use. If so, you can de-clutter your toolbars by getting rid of any unwanted tools. For example, one tool I never use is the Underline. Instead of leaving on the formatting toolbar, I can get rid of it.

The quickest way to get rid of an unwanted tool is to hold down the Alt key and click-and-drag the tool off the toolbar. The tool will automatically disappear. To get the tool back, right click the appropriate toolbar and click Customize. Select the Commands tab, select the tool you previously got rid of then drag it back onto the toolbar.
