Placing the mouse pointer over a menu choice or a button shows a tooltip containing the name of the tool, a keyboard shortcut (if applicable), and a brief description of the tool.
Some tooltips on the application menu, Quick Access toolbar, and ribbon are progressive. If you leave the cursor over the menu choice or a button for another moment, the tooltip may expand to show additional information.
While the tooltip is visible, you can press F1 for context-sensitive help that provides more information about that tool.
