Shell               <F9> or <Alt F><O> or <Esc><F><O>
    -------------------------------------------------------------------------

    Invokes a DOS shell.  While in the shell, you can execute DOS and
    other commands.  When you are ready to leave the shell, type
    "exit <Enter>".  You will be back in QEdit, exactly where you
    left off.

    | QEdit Tip:                      |
    |   You should NOT execute any    |
    |   TSR (terminate and stay       |
    |   resident) programs here.      |
    |   These include the DOS PRINT   |
    |   and GRAPH commands and        |
    |   memory-resident programs      |
    |   such as Sidekick and Superkey.|
    +---------------------------------+

    Once in the shell, QEdit will optionally append "[QE]" to the DOS
    prompt string, provided that:

    1) You have defined the prompt environment variable.
    2) There is enough space left in the environment.
    3) You have set the "Change DOS PROMPT during a Shell" option to
       [Y]es.  See QCONFIG, under Advanced options.

    QEdit TSR will append "[QT]" to the prompt.

    The prompt modification option was added in QEdit v2.1
