The Command Queue Window
************************

When the user presses a command button, the commands associated with that button
are added to a queue. Commands are then extracted from the queue one at a time
and executed.

The VDAT command queue window, shown in the right image, allows the user to monitor the
status of the queue. Each entry in the queue is shown with a name composed by
the name of the button pressed and of the command. E.g. the selected item has
been inserted pressing a button called "Raw to deformer" and will execute the
command "extractfits". Hovering over one item will show a tooltip with the full
command string, as shown in the image below. See :doc:`/command_interpreter` for
details on the structure of the command string.

Commands can be removed from the queue by selecting them and hitting the
:kbd:`Delete` key. Apple computer users might need to use :kbd:`fn + Delete`.
