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.
