\section{Spaces in Mathematics}

Because appropriate spacing for mathematics is provided automatically, you
don't need to use the spacebar to type additional ordinary spaces. In fact,
the spacebar doesn't work if the insertion point is in \hyperref{math}{}{}{%
Math_text.tex}. However, in some situations the program doesn't have enough
information to space your mathematics exactly as you want it and you may
occasionally want to add a little extra space to an expression. These spaces
are provided:

\begin{tabular}{ll}
\textbf{Space} & \textbf{Size} \\ 
Em space & width of M \\ 
2-em space & width of MM \\ 
Normal & 1/6 em \\ 
Required & 1/6 em \\ 
Non-breaking & 1/6 em \\ 
Thin space & 2/9 em \\ 
Thick space & 5/18 em \\ 
Zero space & 0 em \\ 
Negative thin space & -2/9 em \\ 
\hyperref{Italic correction}{}{}{Italic_correction.tex} & depends on
character to the left \\ 
\hyperref{Custom space}{}{}{Custom_space.tex} & as specified
\end{tabular}

\subsubsection{$\blacktriangleright $\quad To enter space}

\begin{enumerate}
\item  Place the insertion point where you want the additional space.

\item  Click\FRAME{itbpF}{21.0625pt}{18.8125pt}{2pt}{}{}{space.wmf}{\special%
{language "Scientific Word";type "GRAPHIC";display "PICT";valid_file
"F";width 21.0625pt;height 18.8125pt;depth 2pt;original-width
18.75pt;original-height 16.9375pt;cropleft "0";croptop "1";cropright
"1";cropbottom "0";filename 'Space.wmf';file-properties "XNPEU";}}, or from
the Insert menu, choose Spacing and then choose Horizontal.

\item  Choose the space you want from the Spaces dialog box.

\item  Choose OK.
\end{enumerate}

Some spaces have \hyperref{keyboard shortcuts}{}{}{Keyboard_shortcuts.tex}%
