Controls the double click editing behavior in the drawing area.
Double click actions can be customized using the Customize User Interface (CUI) Editor.
The system variable can accept the values of On and Off in place of 1 and 0.
Note: The DBLCLKEDIT system variable must be set to On and the PICKFIRST system variable must be set to 1(the default) for double-clicking to work.
You can double-click most objects to open the Properties palette when the DBLCLKEDIT system variable is set to On (the default). The exceptions include blocks and attributes, text, multilines, and xrefs. If you double-click any of these objects, an object-specific dialog box is displayed instead of the Properties palette.
