Edit Mode performs a similar function to Select Mode. The difference being that in Edit Mode items are automatically selected as the cursor is moved over them. A single click will perform the default edit operation, just as the double click performs in Select Mode.
Edit Mode will remain the default operation (after you have cancelled any other interaction), until Select Mode is invoked.
