`Query Tool Toolbar`:index:
***************************
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.
