\textsubplus{e}
\=*{e}
-\b{e}
+(don't mix up with \b{e})

$\textipa{\tone{55}|\text{\!b{}\!d{}\!g{}\!G{}\textglobfall{}\textvertline{}\textdoublevertline{}}}$
+\subsection{Other symbols}
+All three should be converted to U+00C5: \AA{} \r A \r{A} (not U+212B).
+All three should be converted to U+00E5: \aa{} \r a \r{a}.

\subsection{Line breaks\sindex[breaks]{Line breaks}}
They can also or be broken by a newline\\
ellipsis\ldots, and end-of-sentence\@. LyX also supports a menu
separator\lyxarrow{}and a spif\textcompwordmark{}fy ligature break.
+There are dashes: endash in short form -- and long form \textendash,
+emdash is alike: --- and \textemdash. If we really want several hyphens
+in a row, we need to separate them: -{}-, -{}-{}-, -{}-{}-{}- etc.
+
LyX translates the phrases LyX, TeX, LaTeX2e and LaTeX
to the commands \LyX{}, \TeX{}, \LaTeXe{} and \LaTeX{}.
If these phrases occur as part of other words (like 1LyX or aTeX or LaTeX3)
