The Widget Dock is a column of mini-Widget icons that initially appears at the right edge of the desktop. It's a handy at-a-glance way of keeping on top of the information or entertainment the Widget handles. The dock can be at the top, bottom, left, or right edge of the desktop.
With the mode setting, you configure which Widgets the Dock displays: all possible Widgets or only those widgets that are actively working on your desktop. On a 1400 by 1050 pixel screen, the dock can show a row of up to 16 Widgets.
When you move the cursor to the dock, it displays two additional areas of clickable icons. At the top or left, there is a gear icon for a settings menu, a magnifying glass icon for Yahoo! Search, and a plus or a minus sign for the mode setting. At the bottom or right there is space for navigation icons for scrolling between rows or columns of mini-Widgets. Between these navigational icons is an icon for turning on the Heads Up Display that shows all the Widgets currently on your desktop.
