Tooltips provide information about a tool in the user interface or an item in the drawing area, or instructions on what to do next when using a tool.
When you hold the cursor over a tool on the ribbon, by default Revit displays a tooltip. The tooltip provides a brief description of the tool. If you leave the cursor over the ribbon tool for another moment, additional information displays, if available. While the tooltip is visible, you can press F1 for context-sensitive help that provides more information about that tool.
These tooltips are useful when you are first learning how to use the software. You can adjust the amount of information displayed in tooltips or how quickly the information displays. You can also turn off the tooltips when you no longer need them.
When you are working in the drawing area, Revit displays a tooltip near the cursor. This same information is repeated in the status bar.
To turn off these tooltips, define the Tooltip assistance option as None, as described below.
