\chapter{A Guided Tour of Andrew

}
Welcome to the Tour of Andrew.  This document is designed to guide you through 
a general tour of the Andrew system.  If you have never used Andrew, you 
should read the next five paragraphs.  If you have used Andrew before, go on 
to the section called \bold{How to see more help documents} below.


\leftindent{\bold{For those who have never used Andrew.}   The information you 
are reading appears inside a window that contains help information.  The mouse 
is the small box attached by a cord to the workstation.  When you move the 
mouse, the mouse cursor (arrow) on the screen will move.  You should move the 
mouse cursor into the Help window containing this information now.


\bold{To see more of this text:}  Move the mouse cursor into the vertical bar 
at the left edge of the Help window.  This vertical bar is the 
 \italic{scrollbar }.  To move down in the text, click the left mouse button. 
 To move up, click the right mouse button when the cursor is in the scrollbar. 
 The whole scrollbar represents the text; the white box in the scrollbar 
represents the part of the text that is shown on the screen.


\bold{To use the menus:}  Most windows contain sets of  \italic{menus }. 
  Choosing options from these menus allows you to change your work or to use 
various features of a program.   On a two-button mouse, press and hold down 
both mouse buttons to cause the menus to appear.  (On a three-button mouse, 
press and hold down the middle mouse button.)  To choose a menu option, keep 
the button(s) pressed while moving the cursor to the menu item you want.  When 
the menu item becomes darkened, let go of the button(s) to choose it. 


}\section{How to see more help documents}

\leftindent{
There are three ways to ask Help to display different documents.  The 
documents you request will take the place of the document(s) that are 
currently displayed in the Help window.

\leftindent{
\bold{1. Click on the panels.}  At the right side of the Help window, there 
are two panels containing the names of Overviews (top panel) and Programs 
(bottom panel).  For an overview of how to do a particular kind of task, such 
as Writing documents or using the Mail system, point the cursor at a name in 
the top panel and click the left mouse button.  For information about a 
particular program, such as Messages or EZ, click on one of the program names 
in the bottom panel.


\bold{2. Type in a keyword. } You can also provide Help with a "keyword" about 
which you want more information.  With the mouse cursor into the Help window, 
press both (or the middle) mouse button(s) to expose the Help menus.  Choose 
\bold{Show Help on ...} from the menus.  When the following prompt appears at 
the bottom of the Help window:


\leftindent{Enter a keyword about which you want more help:}


type in the keyword you want (e.g., ez, messages).   


\bold{3. Ask for help on a selected word. } Many keywords appear in 
  \italic{italic}  in help documents so that you know there is more 
information about them.  You can pick these words from a help document and ask 
for help about them.  To get help on a word, you must \italic{select}  it.  To 
select a word:

\smaller{
}\leftindent{1.  Point the mouse cursor at the beginning of a word and click 
the left mouse button once.

2.  Hold the left mouse button down and drag the cursor to the end of the 
word.

3.  Release the button to complete the selection.  A dark box appears around 
the word.}


After selecting a word, get help on it by bringing up the menus (by pressing 
both mouse buttons down at the same time) and choosing \bold{Show Help on 
Selected Word}.  If there is no help for the word you have selected, the 
following message appears:


\leftindent{Sorry; no help available on\italic{ 'word'.}}}


\leftindent{If you want, for example, you can select the word  \italic{select 
} , choose \bold{Show Help on Selected Word}, and learn about alternate 
selection mechanisms, and how selected regions relate to the scrollbar.}


}\section{What is Andrew, exactly?

}
\leftindent{The Andrew System, or "Andrew," is a set of computer tools that 
you can use to write and edit documents, send and receive mail, read bulletin 
boards, write your own programs, and do many other activities.  The tools that 
you use on Andrew, such as the editor you use to create documents, are 
computer programs designed to help you accomplish the work you need to do.  }


\section{For More Information}


\leftindent{At the end of many help documents (including this one) is a 
section called "Related Tools."  You can depend on this section to present the 
names of task areas or programs which have functions similar to the one you 
are reading about.   Use these names (we call them keywords) to "shop" for the 
program you want to read about by selecting one of the keywords and using the 
menu option \bold{Show Help on Selected Word}.
