LaTeX: Prevent line break in a span of text

Question

How can I prevent LaTeX from inserting linebreaks in my \\texttt{...} or \\url{...} text regions? There\'s no spaces inside I can replace with ~

Answer 1

Also, if you have two subsequent words in regular text and you want to avoid a line break between them, you can use the ~ character.

For example:

As we can see in Fig.~\ref{BlaBla}, there is nothing interesting to see. A~better place..

This can ensure that you don't have a line starting with a figure number (without the Fig. part) or with an uppercase A.
