°Hypertext                 Hypertext Introduction
                           ──────────────────────

  Hypertext is a technique for interconnecting information for the purpose
of making it easier to locate desired sections of that information.  You
can think of Hypertext as a sort of bookmark and index system. You can, with
a single key, go off to look at some information related to what you are
currently looking at. When you are done looking at that other information,
you can return to where you were with another single key.

  Lets try it to see how it works.                   ∙Other-Information

  Notice the word pair shown above shown in reverse video; press the TAB
key to move to that word.  Now you are ready to "link" to
Other-Information.  You can perform the link in one of three ways:

        Press Enter             Press F9                Press Alt-B
(links ONLY while browsing)  (the link key)           (B meaning BROWSE)

  Press any of the above keys NOW!     When you come back unlink with ∙F10 .

°Other-Information     Other information on Hypertext
                       ──────────────────────────────

   You are now at least +3 levels down in the Hypertext links. The number
 you see at the upper right hand corner of the screen tells you how many
 links FORWARD have been performed. Each time you link forward (like an
 index) to a new piece of information, your previous location is saved
 (like a bookmark).  You can link forward exploring new information up to
 twenty (20) times before the link save stack fills up.

   When it comes time to "unlink", The ∙F10 key will unlink to the exact
 previous place where you linked from.

   This Hypertext system is really implemented as a special "mode" of the
 SED editor. You are in fact in the SED editor now, in what I call BROWSE
 mode.  You are allowed to look around, but you can't make any changes.



        Press ∙F10 to UNLINK,        or          Press PgDn for more.

                        More Information on the Browser
                        ───────────────────────────────

   Certain keys perform special functions while in BROWSE mode. As
 mentioned before, the TAB key moves to the next reverse video link, and
 Enter performs a link to the current word under the cursor.

   BROWSE mode is indicated visually by the word BROWSE in the upper left
 corner, and the double line screen border.

   In Browse mode, you can use the editor PgDn & PgUp as well as Arrow
 keys to move through a file, or you can move the cursor to a word of
 interest, and press F9 or Enter to link directly to that topic.

   If you are nested deeply into a complex browse, you can Unnest quickly to
 the top level edit or browse, by using the File menu command "Unlink to
 level one". The key sequence for this command is Shift-F10 or ESC-F-U.

        Press ∙F10 to UNLINK

°*Menus&Mouse*            Menu & Mouse Control   Press ∙F10 to pop Help level
                          ────────────────────
  SED provides both pulldown menus, and fairly complete mouse support.
Select ∙*Menus* for a description of using pulldown menus with the
keyboard.

  To use a mouse in SED you must have a compatible mouse driver (like
MOUSE.COM) already installed in your autoexec.bat. When F-PC starts up, it
looks for the presence of a mouse driver, and activates the mouse if the
driver is present.

  As you are looking at this screen you will see arrows to the right and
lower right of the screen. These arrows can be used to scroll the screen,
showing more text from the direction the arrow is pointing by clicking the
left mouse button. The ∙F10 or +1 etc. in the upper right corner can be used
like the ∙F10 key by positioning the mouse and clicking the left button.
You can also change the INSERT/OVERWRITE mode by clicking at the top left
of the screen on INSERT. Help can be obtained by pressing HELP at the lower
left. The cursor can be positioned by clicking within the edit window with
the left mouse button.  The right mouse button is the same as the ESC key.

°*Menus*                Using Pull Down Menus    Press ∙F10 to pop Help level
                        ─────────────────────

   SED uses Pull Down menus to make many functions available while editing.
Press the ESC key NOW to see the menubar appear at the top of the screen.

   If you have pressed the ESC key, then you are looking at a list of menu
 titles starting with "File" which should be shown in reverse video, through
 "Help" on the right.  Use the keypad right arrow key to walk along the
 menubar. As you press right arrow, the hilighting moves along the menubar.
 Continue to press right arrow until "File" is again the hilighted menu. Now
 press down arrow to pull the menu down.  Notice the last two items of the
 "File" menu, Exit and Quit.  To the right of these menu items are
 displayed the shortcut keys F10 and Alt-F10. Any menu function can be
 performed with the shortcut key rather than moving through the menu and
 pressing Enter.  If you press the right arrow while the "File" menu is
 pulled down, you will walk along the menu bar with each menu "open", so
 you can see what menu items are available.  You can also press the first
 CAPITALIZED letter of a menu item to perform the item.

   SED can "Shell" to DOS with "ESC F C" under the FILE menu.  This is useful
 for manipulating files on a disk that is TOO full to save to, or to go out
 and format a new disk if needed.  You can even run other programs from within
 the editor if you need to.  Type EXIT to get back to SED.

°F10                     What is the F10 key for?
                         ────────────────────────

   The F10 key "unlinks" or leaves one edit/browse level. If you were
 editing, your changes are saved, and you will return to the previous file
 you were editing or browsing. If you were at the first level of editing,
 F10 will leave the editor to a screen to choose new file.

   The Shift-F10 key will take you to edit/browse level one.  This saves you
 from having to unlink through many levels with F1, and takes you directly
 to level one.  If you were already on level one, Shift-F10 will leave the
 editor.

   Clicking the left mouse button on the F10, +1 or +2 at the upper right
 hand corner will do the same as pressing the F10 key.



        Press F10 now to return to where you were before coming here.

                   ──────────────────────────────────────

   Though the File Open command ESC-F-O or Ctrl-O you can open up to 20
 files while in the F-PC editor.  When you open more than one file F-PC
 keeps track of where you were in each file, but only really edits one file
 at a time.  Files get swapped in and out of memory as required. This is
 slower than keeping all of the file in memory, but on a hard disk system
 the performance is still acceptable.

   Alt-F1 can be used to rotate through the file that have been opened.
 Its reverse command is Shift-Alt-F1 which will rotate through the open
 files in the opposite direction.

   Shift-F1 will popup a window for you to select a particular file
 directly, avoiding the time required to rotate through several files to
 get to the one you want.

   To leave the editor, and close all files, use the File menu command
 ESC-F-X.
