To Open the Search Tab

To temporarily display the Search tab, pause the pointer over the Search roll-out tab.
The Search tab displays along the right edge of the Dependency Viewer tab, and remains displayed as long as the pointer is over the Search roll-out tab. Move the pointer away and the tab is hidden again.
To dock the Search tab, pause the pointer over the Search roll-out tab, and then while the tab is displayed, click the Auto Hide (push-pin) icon in the upper-right corner of the tab.
The Search tab is docked along the right edge of the Dependency Viewer tab. Notice the Properties and Block Filter tabs are also now docked, behind the Search tab.
