Use the default termination character (CTRL/P) to
  suspend a recording session. You can then issue a
  Record control key sequence.

  The following table contains the Record control key
  sequences.

  Key
  Sequence  Function

  CTRL/P B  Starts an automatic screen comparison and
            ends a manual screen comparison for terminal-
            based tests. This control key sequence does
            not apply to DECwindows tests.
  CTRL/P !  Invokes a text editor so that you can enter
            a comment into the session file. You end
            the comment by pressing CTRL/Z. This control
            key sequence is not available for DECwindows
            testing.
  CTRL/P E  Ends an automatic screen comparison and
            begins a manual screen comparison for
            terminal-based tests. This control key
            sequence does not apply to DECwindows tests.
  CTRL/P    Ends the recording session and returns
  CTRL/P    control to the previous command level. When
            you terminate a recording session this way,
            DTM saves the session and benchmark files.
  CTRL/P ?  Displays the current screen comparison mode
            and lists the available recording functions.
            This control key sequence is not available
            for DECwindows testing.
  CTRL/P I  Inserts an input file into the session file
            you are recording. DTM prompts you for the
            input file specification. Input files are
            available for interactive terminal tests
            only.
  CTRL/P C  Marks a screen for comparison. This is the
            only way to mark screens for DECwindows
            tests. You must mark the specific screen
            that you want to compare for DECwindows
            tests. DTM automatically compares all screens
            for terminal-based tests. This control key
            sequence is used in terminal-based tests when
            automatic comparison is disabled.
  CTRL/P    Terminates an interactive recording session,
  CTRL/Z    saves the session file, creates (or modifies)
            the test description, but does not save the
            benchmark file.
  CTRL/P W  Invokes a prompt for you to specify a wait
            time. You issue this control key sequence
            at the place in a session file that you want
            the wait to occur. When the session file is
            subsequently played or executed, the wait
            time is included in the session file.
  CTRL/P    Aborts an interactive recording session
  CTRL/C    without saving any of the generated files.
