Function Synopsis

noselection( state, fig )

Help text

NOSELECTION Select/Deselect all objects in Figure.
   NOSELECTION SAVE finds all objects with the Selected property 
   of 'on'. Turns them all 'off'. Saves the handles so the Selected
   values can be restored. This is useful when printing so that we
   do not print the selection handles.

   NOSELECTION RESTORE returns any previously changed objects'
   Selected properties to their original values.

   NOSELECTION(...,FIG) operates on the specified figure.

   See also PRINT.
