`Tree Control`:index:
*********************

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.

    :alt: object explorer panel
    :align: center

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.

You can also **drag and drop** certain objects to the Query Tool which
can save time in typing long object names. Text containing the object name will be
fully qualified with schema. Double quotes will be added if required.
For functions and procedures, the function name along with parameter names will
be pasted in the Query Tool.

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):
