When pre-selection is turned on, tooltips are displayed when you hover over elements, telling you what the elements are. This can help you when selecting elements, as it lets you know what you are about to select. By default, pre-selection is enabled. On some systems, disabling pre-selection can improve program speed.
To enable or disable pre-selection:
Select Settings
> Program Settings or click the Program Settings button on the
Settings toolbar.
In the Program Settings dialog, select the Drawing Aids tab.
In the Visual Aids area, check or uncheck the Enable Pre-Selection check box.
Click OK.
