Since all chars are letters, the {} are not handled. Another escape is
using <<if>> and option=slanted.

You could try: 

  \def\Key#1#2x{\underbar{#2}}

(the spaces are important)

  .... ?Key ifx 

that way the x acts as sentinel. 

Even better: 

\def\IfKey{\underbar{if}}

  .... ?IfKey .... 

I would go for the last alternative.

Commands in verbatim

[Zeljko Vrba]

I'm writing a manual for a programming language. All examples should be
in \starttyping \stoptyping pairs. However, I'd like to have underlined
keywords. However, the following doesn't work:

\setuptyping[escape=\\]
\starttyping
  \underbar{keyword}
\stoptyping

I don't get the underlined keyword, but the exact above text.
I've tried other escape characters, but none of them work. Is the escape
option intended for this, anyway? How could I accomplish such a task?
