 ShowPatterns [MagicWB] [[not] screenlist]

 Sets the screens on which the patterns will be shown.
 For example:

 ShowPatterns MagicWB
    Patterns will be displayed on all screens that have a palette that
    resembles the MagicWB color setup (the first 8 colors).
    For 4-color patterns, it's enough that the first 4 colors resembles
    MagicWB (or the standard WB2+ color palette). 
 
 ShowPatterns Workbench DM.1
    Patterns will be displayed on the screens Workbench and DM.1
 
 ShowPatterns not BPPScreen ProWrite
    Patterns will be displayed on all screens except BPPScreen and ProWrite.
 
 ShowPatterns MagicWB not Ibrowse
    Patterns will be displayed on all screens that have a palette that
    resembles the MagicWB color setup (the first 8 colors) - but not
    on the screen "Ibrowse" even if it resembles the magicWB palette.

 ShowPatterns MagicWB DM.1
    Patterns will be displayed on all screens that have a palette that
    resembles the MagicWB color setup, AND on the screen "DM.1" even if
    it doesn't resemble the magicWB palette. (Differs from Selector 9.1)

        
 Default is all screens
 
 Please note that a pattern never is displayed if it has more colours than
 the screen has.
