************************
The pgAdmin Tree Control
************************

The left pane of the main window displays a tree control (the *pgAdmin* tree control) that provides access to the objects that reside on a server. 

.. image:: /images/main_left_pane.png

You can expand nodes in the tree control to view the database objects that reside on a selected server. The tree control expands to display a hierarchical view: 

* Use the plus sign (+) to the left of a node to expand a segment of the tree control. 
* Click the minus sign (-) to the left of a node to close that node. 

Access context-sensitive menus by right-clicking on a node of the tree control to perform common tasks. Menus display options that include one or more of the following selections (options appear in alphabetical order):
