First a general note: The Braille you can create with \SpecialChar LaTeX
|
|
is not complete!
|
|
Braille can have 6 or 8
|
|
\begin_inset space \thinspace{}
|
|
\end_inset
|
|
|
|
dots, while \SpecialChar LaTeX
|
|
(and therefore \SpecialChar 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 \SpecialChar 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 \SpecialChar 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
|
|

|
|
width "100line%"
|
|

|

|
|
\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

|

\end_layout

\end_layout
|
|
|
|
\begin_layout Standard
|

\begin_inset VSpace bigskip

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

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
|
|
status open
|
|
|
|
\begin_layout Plain Layout
|
|
6145
|
|
\end_layout
|
|
|
|
\end_inset
|
|
|
|
|
|
\end_layout
|
|
|
|
\begin_layout Standard
|
|
\begin_inset VSpace bigskip
|
|
\end_inset
|
|
|
|
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
