\section{Inserting Text and Mathematics\label{Inserting Mathematics}\label%
{Mouse pointer}\label{Cursor}}

The blinking vertical line on your screen is referred to as the \emph{%
insertion point}. You may have heard it called the \emph{insert cursor}, or
simply the \emph{cursor}. The insertion point marks the position where
characters or symbols are entered when you type or click a symbol. You can
change the position of the insertion point with the arrow keys, or by
clicking a different screen position with the mouse. The position of the
mouse is indicated by the \emph{mouse pointer}, which assumes the shape of
an I-beam over text and an arrow over mathematics.\bigskip

\subsection{\ Basic Guidelines\label{Text/Math}\label{Toolbars}}

In \textsl{Scientific Notebook},

\begin{itemize}
\item  \emph{Text} is entered at the position of the insertion point when
the \textsf{Toggle Text/Math} button in the \textsf{Math Toolbar} shows%

\item  \emph{Mathematics} is entered when the \textsf{Toggle Text/Math}
button shows\FRAME{itbpF}{0.3009in}{0.3009in}{0.0701in}{}{}{math.wmf}{%

\end{itemize}

On the screen, mathematics appears in red and text in black.

\strut

\begin{quotation}
\emph{Tip}\textbf{\quad }The state of the \textsf{Toggle Text/Math} button
reflects the state at the position of the insertion point.
\end{quotation}

\strut

You can toggle between these two states by clicking the buttons shown
earlier or by pressing \textsc{ctrl + m} or \textsc{ctrl + t} on the
keyboard. Entering a mathematics symbol by clicking a button on a toolbar
automatically puts the state in mathematics at the position in which the
symbol is entered. The state remains in mathematics as you enter characters
or symbols to the right of existing mathematics, until you either toggle
back into text or move the insertion point into text by using the mouse or
by pressing \textsc{right} \textsc{arrow}, \textsc{left} \textsc{arrow}, or 
\textsc{enter}. (You can customize your system for toggling between
mathematics and text in the \textsf{User Setup, Text/Math} dialog box under 
\textsf{Tools}. This includes additional choices of toggling with the space
bar or the insert key. See the \textsf{Help} menu for further details.)

Mathematics is automatically spaced differently from text as you enter
it---for example, ``$2+3$'' rather than ``2+3''---so you do not have to make
adjustments.\label{Fraction}\label{Exponent}\label{Subscript}

\strut

You \emph{select }\label{Select}a piece of mathematics by holding down the
left mouse button while moving the mouse, or from the keyboard by holding
down \textsc{shift} and pressing \textsc{right} \textsc{arrow} or \textsc{%
left} \textsc{arrow}. Your selection appears on the screen in reversed
colors. This technique is sometimes referred to as ``highlighting'' an area
of the screen.

You can change the state of an expression by selecting that expression and
then either clicking the \textsf{Text/Math} button, pressing \textsc{ctrl + m%
}, or pressing \textsc{ctrl + t}.

\strut

\subsection{\ Displaying Mathematics\label{Displaying mathematics}}

Mathematics can be centered on a separate line in a \emph{display}. \label%
{Display}You can create a display and enter mathematics into it. 
\[
z=\sqrt{x^{2}+y^{2}} 
\]

\begin{quote}
$\blacktriangleright $ To create a display
\end{quote}

\begin{enumerate}
\item[1.]  Click \FRAME{itbpF}{0.2992in}{0.2992in}{0.0692in}{}{}{display.wmf%
}{\special{language "Scientific Word";type "GRAPHIC";maintain-aspect-ratio
TRUE;display "PICT";valid_file "F";width 0.2992in;height 0.2992in;depth
0.0692in;original-width 17.8125pt;original-height 16.9375pt;cropleft
"0";croptop "1.0179";cropright "1.0179";cropbottom "0";filename
'Display.wmf';file-properties "XNPEU";}}, or from the \textsf{Insert} menu,
choose \textsf{Display}.

\item[2.]  Type a mathematical expression in the display, or select a piece
of mathematics and drag it into the display.
\end{enumerate}

\strut

\begin{itemize}
\item  Inserting \textsc{enter} immediately before a display will add extra
vertical space. If you do not want this space, place the insertion point
immediately before the display and press \textsc{backspace}.

\item  Inserting \textsc{enter} immediately after a display will add extra
vertical space and cause the next line to start a new paragraph. If you do
not want this space, place the insertion point at the start of the next line
and press \textsc{backspace}.
\end{itemize}

\strut

You can begin with an existing mathematical expression and put it in a
display.

\begin{quote}
$\blacktriangleright $ To put mathematics in a display
\end{quote}

\begin{enumerate}
\item[1.]  Select the mathematics with click and drag or \QTR{KeyName}{%
shift+right arrow}.

\item[2.]  Click the \textsf{Display} button on the \textsf{Math} toolbar,
or from the \textsf{Insert} menu, choose \textsf{Display}.
\end{enumerate}

If you press \textsc{enter} after the display, the next line will indent to
start a new paragraph. Otherwise, the next line will begin at the left
margin in the same paragraph as the display.

\strut

\begin{quote}
$\blacktriangleright $ To remove an indent after a display
\end{quote}

\begin{enumerate}
\item[1.]  Place the insertion point at the left of the first indented word.

\item[2.]  Press \textsc{backspace}.
\end{enumerate}

\strut

The default environment in a display is mathematics. You can, however, enter
text in a display by toggling to text. Also, you can select mathematics or
text in a display and change its state by toggling in the standard ways.

\subsection{\ Centering Graphics and Text}

\strut

\label{Display text}If you have text that you wish to center on a separate
line, the natural way to do this operation is with \textsf{Body Center}%
\QTR{MenuDialog}{,} which you can choose from one of the pop-up menus at the
bottom of your screen.

If you have a graphic that you wish to center on a separate line, you should
choose the \textsf{Display} setting in the \textsf{Frame Properties} dialog,
as discussed in \hyperref{Plotting Curves and Surfaces}{}{}{%
DM6-2.tex#Display frame}. To center a group of graphics, you can use \textsf{%
Body Center}. We generally advise against placing a plot inside the \textsf{%
Insert + Display} object.
