To modify the properties of a panel application, you must first right-click on the panel application to display the panel object popup menu. To move a panel application, you must middle-click on the panel application.
Some restrictions apply on where you can click on a panel application in order to display the panel object popup menu, or to move the panel application, as follows:
Some panel applications have popup menus of panel application-specific
commands that open when you right-click on particular parts of the panel application.
For example, the Window List
panel application
has a vertical handle on the left side, and buttons that represent your windows
on the right side. To open the panel object popup menu for the Window List
panel application, you must right-click on the handle.
If you right-click on a button on the right side, a popup menu for the button
opens.
Some panel applications have areas that you cannot use to
select the panel application. For example, the Command Line
application has a field in which you enter commands. You cannot middle-click
or right-click on this field to select the panel application. Instead, middle-click
or right-click on another part of the panel application.
