Dialog box launcher

A dialog box launcher is a button in the Ribbon of Microsoft Word, Excel, Outlook, and PowerPoint used to reveal additional tools available for use in that section of the Ribbon. Because there isn't room to show all tools in the Ribbon, click the dialog box launcher to see the features and options that are hidden. In the picture of the Excel Ribbon below, there are four dialog box launchers highlighted by red boxes.
