Widget Bar

The Widget Bar in Dashboard gives the user access to all installed widgets. If the total number of widgets exceeds the number shown on one screenful, arrow buttons are added.

Use
Display the Widget Bar by clicking the + (plus) button. Hide it by clicking the X button.

Drag a widget out from the Widget Bar, or click it once, to be able to use it in Dashboard. Beginning with Mac OS X 10.4.2, the Widgets icon at the left side can be used to enable or disable individual widgets.
