To Replace a Control in the Main Panel
The easiest way to replace a control in the Main Panel is to exchange it with a subpanel control. If the control does not have a subpanel, you can create one temporarily or permanently.
If the control you want to replace does not have a subpanel, create one by choosing Add Subpanel from the control's pop-up menu.
Display the new subpanel.
If the control you want to put in the Main Panel is not already in the subpanel, add it to the subpanel.
See "To Add an Application or Other Icon to a Subpanel".
Choose Copy to Main Panel from the subpanel control's pop-up menu.
