\texttt{foo} vs \verb#foo#

The LaTeX commands `\texttt` and `\verb` are very similar, but not the same:

• `\verb` uses the next character as the delimiter, not braces
• `\verb` will not break over a line (and will happily encroach into the margin)
• `\verb` (and the `verbatim` environment) in a Beamer slide needs the `fragile` attribute

I tend to prefer `\verb`, as I never want monospaced text to be broken over a line.
