Several types of tooltips provide pop-up information for interaction with toolbars,
object snaps, and drafting operations.
Tooltips are displayed for buttons and options in toolbars, the Application menu,
the ribbon, and dialog boxes. When the cursor is over a ribbon button, for example,
a basic tooltip is displayed. If you continue to hover, the tooltip expands to display
additional information. You can customize the display and content of a tooltip in
the Options dialog box.
