When starting an interactive PostScript process with M-x ps-run-start (ps-run-start), a second window will be displayed, and ps-run-mode-hook will be called. The keymap for this second window is:

When Ghostscript encounters an error it displays an error message with a file position. Clicking mouse-2 on this number will bring point to the corresponding spot in the PostScript window, if input to the interpreter was sent from that window. Typing C-c C-e (ps-run-goto-error) when the cursor is at the number has the same effect.

Probably introduced at or before Emacs version 21.1.
