Reader Mode Links Hypertext documents are based on the concept of links. A links is simply a
connection between two things in such a fashion that the link can be
"traversed" or "activated". More on Links The different types of links are show below in the table. Link Type Symbol Action Note Yellow Diamond Pop Up Note Window Replacement Purple Rectangle Swaps text on screen for

text surrounding the link originator. These symbols are listed above with
their colors for your reference. More On Links Links are dynamic in that a link serves as a uni-directional
gateway to something else in the document. Upon traversing
a link, certain things will happen as a result of it. For example, when a note link is traversed, a window pops up
in the upper right hand corner of the screen containing the predefined note. Concepts & Terminology $ Graphics Chapter Along with hypertext goes terminology and concepts to adequately describe it.

Mapping Reading a hypertext document is surprisingly easy given the dense information
content of the material. There are only a few keys that are necessary to
navigate through a hypertext document, and they are: <F1> Forward Link Traverse <Alt> <F1> Collapse Document <ArrowKey> Movement <Esc> Backwards Link Traverse OR With The Mouse <MOUSE> Movement <LeftMouseButton> Forward Link Traverse <RightMouseButton> Backwards Link Traverse Usual Method Of Reading "Mouse Use Additionally a mouse, may be used to read a hypertext document. NOTE About
Mouse Use. The mouse can be used to read a document in the following fashion. Movement Mouse Buttons Scrolling These abilities to use a mouse as a tool to read a document makes it very
convenient and fast to read documents. Mouse & Editing Besides <F1> and the <ArrowKeys>, there are a few more commands necessary to
use hypertext effectively. <Esc> <Alt> <F1> Additionally there is a special function that was defined to make hypertext
easier to read, the Mapping function. This will display a document as a
graphic representation of reference links, from which any branch can be
quickly reached. Mapping Function
The Mapping command Black Magic includes a command that will display a hypertext document in a
graphic function. This command is the "Map Hypertext" function. It displays a
document as a series of reference links. This command shows the overall
branching and level structure of the document. Additionally any branch of a
document can be accessed here by using the arrow keys to move to its branch
and pressing <Enter>. The mapping command is used by pressing: <Ctrl> <F2>
More On Mapping Using The Map Map Restrictions Reader Mode Black Magic offers a mode in which you can set the computer to remove all of
the editing functions. This command lets you view your document in the same
appearance as the public domain reader program. It justifies text and allows
you to go through a document in a fashion that will prevent any changes to the text. This mode is entered by pressing: <Alt> <F2> To leave this mode is done again press: <Alt> <F2> Using The Map Accessing the map is done with the arrow keys. When the map initially comes
up on screen the current cursor position is highlighted. To move to another
position use the arrow keys. If the document is very large the map will
scroll off the screen. At the top of the screen a window is shown that
contains the first three lines of the text from each section of the map. This
serves to indicate to you what the contents of each section are. To move
directly to any of the sections shown on the map, move the cursor to that
section and press <Enter>. Or to just return to your current position in the
document press <Esc>. To return to the top of the map, simply press <Home>. More On Mapping This will change the screen from a text display to a graphic representation of
the document as chained reference links. This map displays the document as a
series of sections that are connected by reference links. The map is depicted
as a tree structure that stretches down off the screen. The lines between
sections indicate the reference links and their structure, while the sections
themselves represent the link ends for the reference text. The only restriction on using the Map
is that it is limited to 19 levels of
reference link structure. After this
point, the map simply does not
display. The usual method to read a Black Magic document, is to load the file
and then move through it by using the cursor keys or the mouse. When a
hypertext link is encountered, the cursor is positioned on it and then press
<F1>. This activates the link, letting it perform whatever action that has
been assigned to it. For the mouse to function a copy of
MOUSE.COM or the equivalent must be
loaded. Microsoft or Compatible. The movement of the mouse will
substitute for the cursor keys. The mouse buttons will substitute for
<F1> and <Esc>. Moving the mouse off screen will also
scroll the screen slowly in the
direction that the mouse cursor is. Besides the reading of a document with
the mouse, it may also be used for
cursor control during editing. This can greatly speed the editing process. If the typing cursor (as opposed to the
mouse cursor) is not apparent on screen after moving the mouse, click the left
button and it will appear. Just as <F1> is the key that indicates traverse the link forward, <Esc> is the reverse of that - a backwards link traverse. After using <F1> to traverse or activate a link, pressing <Esc> will step backwards through that link. Traversing it backwards so to speak. The other command is <Alt> <F1>, Collapse. This command takes a magic document that is "unfolded" through much reading, and condenses it back to its original form, deactivating all the links. A Link Originator is the "summoning" side of a hypertext link. In terms of creating hypertext, a Link Originator is what was originally designated as hypertext, BEFORE anything was entered to form the basis for the specific type of link (Note, Replacement, etc.). A link end is the destination of the link, it is the
material that the link originator is tied to. It is the
actual material of the link. The third concept is that of the Graphic Indicator. This is a special symbol which looks like a blue circle. It appears just above the graphic image to its right. This symbol will appear next to any graphic image that is in a hypertext document. It simply serves to indicate that an image is present, and it provides a method to manipulate that image using blocks. By defining the Graphic indicator as a block, the image can be cut, copied and pasted through out the document. Example For example, if the word "Benjamin Franklin" has been designated as the basis for a Note link, and the sentence "Ben Franklin was a famous American scholar and statesman" as the material for a Note link, the "Benjamin Franklin" would be the Link Originator, and "Ben Franklin was a famous American Scholar and Statesman" would be the Link End. The fourth concept is that of the Graphic Link. This is a special symbol which looks like a blue circle with an "X" in its center.This symbol will appear near or on any graphic image that is used as a Link Originator. It provides an access for traversing the link. To traverse a link through its Graphic Link , move the cursor onto the symbol and press <F1>. This will traverse the link and put you at the Link End. There can be more than one graphic link per symbol (see the chapter on graphics for more). The first term is the word Traverse, as used in "traversing a link." Traverse means the physical act of moving the cursor onto a link and pressing <F1>; in actuality it is the process of traveling through a link to its destination. For example when a Note link is traversed, you are traveling through the link to the note window that pops up on screen. Just as pressing <F1> initiates a forward link traverse, there are backwards link traverses. A backwards link traverse is indicated be pressing <Esc> anywhere in a Link End, and serves to return you to the Link originator. For example, compare reading a large hypertext
