The Presen(tation) key switches from SET mode to a menu where you can define the presentations.
Initially, the currently set presentation is displayed. A message tells you if more presentations are defined. You can switch from one presentation to the other using the scroll keys.
In such a presentation, the different physical properties are assigned to the sixteen logical attribute names. QUERY only uses the first seven logical attribute names. Each logical attribute name (ATTR1 to ATTR16) is displayed in the menu together with the attributes and colors assigned to it.
The kinds of representation and color available depend on the installation and the system used. If colors cannot be set, the keys 
and 
are not displayed.
To change such an assigment, mark one or more attributes with an "x" and press the keys 
, 
or 
. Popup menus appear where the desired settings for
the coloring and kind of representation can be chosen by checking them with an "x".
The toggle switch 
is used to mark all attributes with an "x". If all attributes are already marked with an "x", this key removes them instead.
The keys 
, 
, 
, 
, and 
have the same functions as in the other SET forms.
