Leaving PS_View can be done through File -> Leave (Esc)
or File -> Quit (and save restart) (F4). In the second case program writes
a file allowing for a future restart, i.e.,
keeping of the same screen position with the document (page, position on
the page, etc.), which allows for the reconstruction of the view at a
subsequent program start. The restart file is by default written into the
current directory. Restart information may also be written or read
without leaving the program with the following menu commands:
File -> Restart -> Save (Save as)
File -> Restart -> Load (Load from).
The restart mechanism allows to get the same screen position for several documents opened at the same time (in different program instances), which might be helpful when e.g., working with color separations. To achieve this one only needs to read in the same restart file.
