\begin_layout Title
How to write Braille with LyX
\end_layout

\begin_layout Author
Uwe Stöhr
\end_layout

\begin_layout Standard
First a general note: The Braille you can create with LaTeX is not complete!
 Braille can have 6 or 8
\begin_inset space \thinspace{}
\end_inset

dots, while LaTeX (and therefore LyX) only supports only 6
\begin_inset space \thinspace{}
\end_inset

dot Braille without accented characters.
\end_layout

\begin_layout Standard
To write Braille with LyX, load the module 
\family sans
Braille
\family default
 in the document settings under 
\family sans
Modules
\family default
.
 Now select the environment 
\family sans
Braille
\begin_inset space ~
\end_inset

(default)
\family default
 or 
\family sans
Braille
\begin_inset space ~
\end_inset

(textsize)
\family default
 from LyX's environment selection box and write your text.
 The other Braille environments are only turn on/off some properties as
 described below; keep them empty!
\end_layout

\begin_layout Standard
Here is an example:
\begin_inset Newline newline
\end_inset


\begin_inset CommandInset line
LatexCommand rule
offset "0.5ex"
width "100line%"
height "1pt"

\end_inset


\end_layout

\begin_layout Standard
with Latin letters:
\begin_inset Newline newline
\end_inset

This is an example sentence written in Braille.
\end_layout

\begin_layout Standard
with Braille letters:
\end_layout

\begin_layout Braille (default)
This is an example sentence written in Braille.
\end_layout

\begin_layout Standard
\noindent
\begin_inset CommandInset line
LatexCommand rule
offset "0.5ex"
width "100line%"
height "1pt"

\end_inset


\end_layout

\begin_layout Standard
\begin_inset VSpace bigskip
\end_inset

You can see that LaTeX is not able to hyphenate words written in Braille;
 you have to do this manually.
\end_layout

 Only Latin letters, numbers, punctuations, parentheses, and brackets can
 be printed in Braille.

\end_inset

, or 
\begin_inset Quotes eld
\end_inset

 - size that approximately matches the document's text size:
\end_layout

\begin_layout Braille (textsize)

\end_layout

\begin_layout Standard

Text can be printed mirror-inverted for embossing the Braille by hand with
 a needle or another suitable device:
\end_layout

\begin_layout Standard
Normal:
\end_layout

\begin_layout Braille (default)

\end_layout

\begin_layout Braille (mirror off)

\end_layout

\begin_layout Standard

Braille characters can alternatively be created by writing a number to a
 Braille box.
 A Braille box is inserted with the menu
\family sans
 Insert\SpecialChar \menuseparator
Custom
\begin_inset space ~
\end_inset

insets
\family default
.
 Every number in this box turns on the corresponding Braille dot.
 For example, the number
\series bold
 6145
\series default
 results in:
\begin_inset Newline newline
\end_inset


\begin_inset Flex Braillebox

\begin_layout Plain Layout

\end_inset


\end_layout

Computer Braille that uses 8
\begin_inset space \thinspace{}
\end_inset

dots can be turned on with the command
\series bold
 
\backslash
brailleeightdotstrue
\series default
.
 But the two extra dots are only printed when using a Braille box.
 For example, the number 
\series bold
8175
\series default
 in a Braille box results in:
\begin_inset Newline newline
\end_inset


\begin_inset ERT
status collapsed
