Besides the point-and-shoot hypertext features 
described under "Quick Commands", Think & Do
programs provide other features to make reading 
text more convenient.  To select any item from 
within the menubar:

     []  Press `F10` to access ~Menubar~
     []  Use your arrow keys to `highlight` 
         the appropriate item
     []  And then press `ENTER` when ready

                           þ Press `F8` Contents 


The ~Files~ menu lets you select files to 
view, drop to DOS, or exit the program 
altogether.

The `Open` item displays a dialog with three
lists:

          []  Files, Directories, and Drives

Each of these is a sorted list.  Entries can
be selected by using your `ARROW` keys, or by 
typing the first letters of the entry.  When 
the appropriate entry is highlighted, press 
`ENTER`.  To move from one list to another, 
press your `TAB` key.

The Open `Files` list displays files in the 
current directory.  To view a file, select 
its name from the list.  If a program -- 
rather than a text file -- is selected, the 
program is launched.

To change the current file mask, press `TAB` 
to move to the `Directories` list and select 
the ".  <current>" entry.

The Open `Directories` list displays sub-
directories.  To change to a subdirectory, 
select its name from the list.

The Open `Drives` list displays available 
drives.  To change to another drive, select
its letter.

The `Dos Shell` item temporarily returns you
to your operating system without exiting the
application.

The `Exit` item closes your application, and 
returns you to DOS.  When you exit the appli-
cation, the program will automatically save 
your current hypertext application so that 
later, when you return to the program again 
your hypertext application will be reloaded...
it will appear as though you had never left.

                           þ Press `F8` Contents


The ~Contents~ menu will display headings (or
labels) found in a text in two different ways:

     []  The `Table` of Contents lists the 
         ~headings~ (labels) sequentially.
         This menu will also highlight the 
         name of the heading currently in 
         view, lending a "you are here" 
         affect.

     []  The `Index` of Contents lists the 
         headings sorted alphabetically.  The 
         index does not "autoseek" the current
         heading, but  remains at the heading    
         selected when it was last used.

To return to a previous screen after using
either menu, press `BACKSPACE`, or 
`SHIFT - F9` for the ~Screen History Menu~.


:NAVIGATE_MENU

                           þ Press `F8` Contents


The ~Navigate~ menu leads to these submenus:

          []  Goto_Menu*
          []  Jump_Menu*
          []  Screen_Menu*


:Goto_Menu

The ~Goto~ menu is a hypertext fastlane; 
instead of bothering with lists, readers 
can input a heading (label) or file names, 
or page or row numbers directly.  This is 
handy for the reader who already knows the 
text well.

`Note`:  The Goto `File` item can also be 
used to launch external programs that need 
command line arguments. Just type the name 
of the program (including the .EXE or .COM 
extension) followed by any parameters as you
would use them at a DOS prompt.


:Jump_Menu

The ~Jump~ command assumes your cursor is on
or next to the name of a ~heading~ (label).  
Pressing `ENTER` is another way to make this
type of jump.  The Jump `File` item assumes 
the cursor is on or next to the name of a 
file: just as if the words were "quoted". 
The `Next_star` and `Prev_star` items move 
the cursor to the next or previous asterisk.


:Screen_Menu

The ~Screen History~ menu specifies the last
line the cursor was on for the ~last 128 
screens viewed~.  To return to a prior screen,
simply ~select~ a line from the `History` list.
If the file is not already loaded, the program 
will try to load it for you.

Screen `Insert` adds the current line to the 
`History` list, just as if you had jumped or 
scrolled from it.  Screen `Insert` is the
hypertext answer to bookmarks.

The `Back_track` and `Retrack` items allow you
to move quickly along the screen `History`.  
After you have back tracked to review a 
screen, you can use Retrack to resume your 
reading.  The screen `History` list works like
an infinite loop: if you Backtrack or Retrack 
long enough, ~you will always return to where
you began~.


:SEARCH_MENU
þÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄþ   
                           þ Press `F8` Contents


The ~Search~ menu provides for two types of 
searches.  The first, called `Find text`, is 
the conventional type of search used by most
any hypertext application:  ~input a word, 
phrase, or text string,~ press `ENTER`, and
the program ~jumps you to the next occurrence~
of that word, phrase, or text string in your 
current file.

Additionally, this program offers a `Global` 
search feature.  This feature will ~quickly 
find every occurrence~ of the given word or
string in a file, ~compile~ a `Hit List` of
the lines containing that word or string, and
then display the list.

You can then scan the `Hit List` for the lines
you want, and jump to them on demand.  The 
`Hit List` remains available until the next
`Global` search, so you can ~jump back and 
forth~ between ~finds~ as needed.

~When searching for text~, this program uses 
the same upper/lower case matching used by 
major word processing programs.  UPPERCASE
letters only match other UPPERCASE letters, 
while lower-case letters match UpperCase and
lower-case letters.

~To search for a whole word~, type a space 
before and after the word.  A single leading 
or trailing space can also be used to find
a prefix or suffix.
