\section{Introduction to Scientific Notebook}

To get started using \textsl{Scientific Notebook}, you can proceed in a very
straightforward fashion. Text entry is natural, with the emphasis on the
content itself rather than on its placement. You use familiar mathematical
notation to enter and display mathematics. You can think and write at the
computer, in much the same way as you have used pencil and paper in the
past. But you have the power of a computer algebra system at your fingertips
to help you explore and experiment.

\subsection{The Main Window}

The first thing you see when you open the notebook is the \QTR{Terminology}{%
main window}. The largest part of the screen is the \emph{entry area}, which
contains the \emph{insertion point} indicating where \textsl{Scientific
Notebook} will insert the next character you type. The top bar in the 
\textsl{Scientific Notebook} screen displays the name of the program and the
current file. Below that is the \textsf{Menu}\QTR{Terminology}{\ bar},
listing menu titles:\medskip

\begin{center}
\textsf{File\quad Edit\quad Insert\quad View\quad Go\quad Tag\quad
Tools\quad Maple\quad Window\quad Help\medskip }
\end{center}

When you choose one of these titles, \textsl{Scientific Notebook} displays a
pull-down menu listing the available commands. \medskip

We will indicate a sequence of choices, such as

\begin{itemize}
\item  Choose the \textsf{File} menu; then from the \textsf{File} menu,
choose the item \textsf{New}
\end{itemize}

by

\begin{itemize}
\item  Choose \textsf{File + New}
\end{itemize}

or simply by

\begin{itemize}
\item  \textsf{File + New}
\end{itemize}

\subsubsection{Scientific Notebook Toolbars}

Beneath the \textsf{Menu} bar, or at the bottom or sides of your screen, may
be several icon bars called \emph{toolbars}. To see the names of the buttons
that appear on the toolbars, let your mouse pointer pause over a button and
a \emph{tooltip} containing the name of the button will appear on the
screen. Two important toolbars for doing mathematics are the \textsf{Math}
and \textsf{Symbol} toolbars.\bigskip

The \textsf{Math}\QTR{Terminology}{\ toolbar}s contain buttons for entering
mathematical objects and buttons representing special tools.\FRAME{dtbpF}{%

"1";cropbottom "0";filename 'Mathbar2.wmf';file-properties "XNPEU";}}\vspace{%
0.25in}

The \textsf{Symbol}\QTR{Terminology}{\ toolbar} contains buttons for
entering symbols and Greek characters.

\FRAME{dtbpF}{3.1972in}{1.0784in}{0pt}{}{}{symbol2.wmf}{\special{language

"XNPEU";}}\bigskip

If these two toolbars do not appear on your screen, from the \textsf{View }%
menu, choose \textsf{Toolbars} and check \textsf{Math1}, \textsf{Math2} and 
\textsf{Symbol} to bring them to your screen.\bigskip

The \textsf{Compute} toolbar is useful for doing mathematics, as it contains
shortcuts for several of the most common mathematical operations on the 
\textsf{Maple} menu: \textsf{Evaluate}, \textsf{Evaluate Numerically}, 
\textsf{Solve Exact}, \textsf{Simplify}, \textsf{Expand}, \textsf{Plot 2D
Rectangular}, \textsf{Plot 3D Rectangular}, \textsf{New Definition}, and 
\textsf{Show Definitions}.\FRAME{dtbpF}{2.6455in}{0.3943in}{0pt}{}{}{%

26.375pt;cropleft "0";croptop "1";cropright "1";cropbottom "0";filename
'Compute2.wmf';file-properties "XNPEU";}}

The toolbars \textsf{Common Symbols}, \textsf{Standard}, and \textsf{Field}
contain shortcuts for editing. You will find these very convenient if there
is room for them on your screen. All of these commands are also available
from other toolbars or from dropdown menus. The toolbars \textsf{Tag}%
\QTR{Terminology}{\ }and \textsf{Fragments} will help you add structure to
your document as you become more familiar with \textsl{Scientific Notebook}. 

The \textsf{Navigate}\QTR{Terminology}{\ toolbar} helps you move around in a
document. This toolbar allows you to jump to section headings and markers by
choosing from drop-down lists, and to jump to the previous or next section%
\FRAME{dtbpF}{4.8352in}{0.4151in}{0pt}{}{}{navigate.wmf}{\special{language

"1";cropright "1";cropbottom "0";filename 'Navigate.wmf';file-properties
"XNPEU";}}

The forward and backward arrows on the \textsf{Link}\QTR{Terminology}{\
toolbar} help you move between documents that are linked. The button on the
left will take you to the \textsf{Table of Contents}. This toolbar also
allows you retrace your movements with \textsf{History Back} and \textsf{%
History Forward}.

\FRAME{dtbpF}{2.2278in}{0.3736in}{0pt}{}{}{linksbar.wmf}{\special{language

"1";cropright "1";cropbottom "0";filename 'linksbar.wmf';file-properties
"XNPEU";}}If these toolbars are not on your screen, look at \textsf{Toolbars}
on the \textsf{View }menu, and check \textsf{Navigate} and \textsf{Link} to
bring them to your screen. Most of the navigating options are also available
on the \textsf{Go} menu.

\subsection{Scientific Notebook Conventions}

The \textsl{Scientific Notebook} screen presents commands in menus and
toolbars. Many of these have associated dialog boxes, as indicated by the
ellipses ($\ldots $) that follow certain menu names and buttons. Like other
programs, \textsl{Scientific Notebook} responds to commands that you enter
using the mouse or the keyboard. Also, \textsl{Scientific Notebook} adheres
to standard keyboard conventions.\medskip

We will generally give instructions in terms of only one option---most
frequently choosing commands from menus, since the configuration of toolbars
on your screen may vary. You will find a list of keyboard shortcuts for
editing commands under Keyboard Accelerators on the Help menu.

\subsection{Mathematics and Text}

Mathematics and text behave differently in \textsl{Scientific Notebook},
both in appearance and function. For example `2+2' and `$2+2$,' entered in
text and mathematics, respectively, have a different spacing between
characters. They also have a different screen color---in most cases text is
black and mathematics is red---to help you interpret objects on the screen.
The same structure that gives mathematics its screen color helps \textsl{%
Scientific Notebook} to identify mathematics for computation.

The \textsf{Toggle Math/Text} button \FRAME{itbpF}{0.2992in}{0.2992in}{%
0.0692in}{}{}{math.wmf}{\special{language "Scientific Word";type

"0";croptop "1.0179";cropright "1.0179";cropbottom "0";filename
'Math.wmf';file-properties "XNPEU";}} when the insertion point is in
mathematics. You can toggle between these two modes by placing the mouse
pointer on the math/text button and clicking with the left mouse button. You
can also toggle from the keyboard with \QTR{KeyTopics}{ctrl + m} or 
\QTR{KeyTopics}{ctrl + t}, or from the \textsf{Insert} menu by choosing 
\textsf{Math} or \textsf{Text} (or by typing \QTR{KeyTopics}{alt + i, m} or 
\QTR{KeyTopics}{alt + i, t}).

\subsection{Terminology Conventions}

We follow terminology conventions established in the \textsl{Scientific
Notebook} documentation.\medskip

\begin{itemize}
\item  \emph{Choose} 
\index{Choose@Choose}\QTR{Extract}{\label{Choose}} means to tell \textsl{%
Scientific Notebook} to carry out a command listed in a menu or shown on a
button in a dialog box.

\item  \emph{Select} 
\index{Select@Select}\label{Select} means to highlight the part of the
document that you want your next action to affect, or to choose a specific
option from a dialog box.

\item  \emph{Check} 
\index{Check@Check}\label{Check} means to turn on a check box option in a
dialog box.

\item  \emph{Click} 
\index{Click@Click} means to position the mouse cursor, then press and
immediately release the left mouse button without moving the mouse. For
example, ``Click the numerator.''

\item  \emph{Double-click} 
\index{Double-click@Double-click} means to position the mouse cursor, and
then click the left mouse button twice in rapid succession without moving
the mouse. For example, ``Double-click the \textsf{Hint Box} to see how to
use \textsl{Scientific Notebook} to solve this problem.''

\item  \emph{Drag} 
\index{Drag@Drag} means to position the mouse cursor, press and hold down
the left mouse button while you move the mouse, and then release the button.
For example, ``Drag from the numerator to the denominator to 
\QTR{Terminology}{select} 
\index{Select@Select} the fraction.'' (The ``selection'' will appear on the
screen with light and dark reversed.) We may also refer to this operation as
selecting ``with the mouse.''
\end{itemize}

\subsection{Copying, Moving, and Deleting Text and Mathematics}

You can move, copy, or delete selections directly with a mouse technique
called ``drag and drop.'' 
\index{Drag and drop@Drag and drop} This has the same net effect as the
Windows or Macintosh ``cut and paste'' feature---the selection is moved (or
copied) from its former position to the point where you released the mouse
button.

\begin{quote}
$\blacktriangleright $ To move text with ``drag and drop''
\end{quote}

\begin{itemize}
\item  Select a portion of text or mathematics or both. You can do this with
drag, as described above, or by holding down \QTR{KeyName}{shift} and
pressing an arrow key.

\item  Without pressing any of the mouse buttons, position the mouse pointer
within the selection.

\item  Press and hold down the (left) mouse button (a scissors icon appears
on the screen).

\item  While holding the mouse button down, drag the mouse pointer to the
position where you want to place the selection. The insertion point follows
the mouse cursor as you do this, providing an accurate guide to where your
selection will appear.

\item  Release the mouse button.
\end{itemize}

\begin{quote}
$\blacktriangleright $ To copy text with ``drag and drop''
\end{quote}

Follow the same steps used for moving text, except either press the \textsf{%
ctrl} key before beginning step 3 or press the right mouse button and hold
it down until the operation is completed (a copy icon appears on the
screen). The net effect is that the selection remains in the original
position, and a copy of it is inserted into the new position as well.

\begin{quote}
$\blacktriangleright $ To delete text with ``drag and drop''
\end{quote}

Follow the same steps used for moving text, dragging the mouse pointer to
the side of the \textsl{Scientific Notebook} window, outside the entry area,
such as to the scroll bar to the right of the window. When you release the
mouse button, \textsl{Scientific Notebook} deletes the text you selected.

\begin{quote}
$\blacktriangleright $ To replace mathematics ``in-place.''\label%
{In-place replacement}
\end{quote}

Select a mathematics expression with the mouse, press the \textsf{ctrl} key
and, while holding it down, choose \textsf{Evaluate} (or another appropriate
command). The expression you selected will be replaced by the result of the
command.

\subsection{The Help Menu}

When you choose the \textsf{Help} menu, you find an on-line help system that
describes editing and computing features of \textsl{Scientific Notebook}.
These are read-only documents. However, you can select material, copy to the
clipboard, and paste into an active document.

The \textsf{Help} menu also offers a wide selection of reference materials
under \textsf{Reference Index} and \textsf{Contents}.
