This section describes the objects that

Some restrictions apply on where you can click on an applet in order
to display the panel object popup menu, or to move the applet, as follows:
Some applets have popup menus of applet-specific commands
that open when you right-click on particular parts of the applet. For example,
the Window List applet 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
applet, 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 applets have areas that you cannot use to select the
applet. For example, the Command Line applet has
a field in which you enter commands. You cannot middle-click or right-click
on this field to select the applet. Instead, middle-click or right-click on
another part of the applet.

Modifying the Properties of an Object

mode. To specify the movement mode, press one of the following keys as you
