***************************
|
|
|
|
The *Query Tool* toolbar uses context-sensitive icons that provide shortcuts to
|
|
frequently performed tasks. If an icon is highlighted, the option is enabled;
|
|
if the icon is grayed-out, the task is disabled.
|
|
|
|
.. note:: The :ref:`Query Tool <query_tool>` and
|
|
:ref:`View/Edit Data <editgrid>` tools are actually different operating
|
|
modes of the same tool. Some controls will be disabled in either mode.
