\begin{document}

The three following lines do the same thing, using the textbf command:

\textbf33 \textbf**

\textbf{3}3 \textbf **

\textbf 33 \textbf{*}*

This space command\ is valid in \LaTeX.

So is this newline\
command and so is this tabular\	command as written in the \TeX book, chapter 3.

Spellchecking woorks too
