It uses the QRegExp class in Qt4, so look up documentation on this;

QRegExp is generally Perl-like, though it does not support some of the  
more advanced features.

\t matches the tab character. I thought \n should match newline, but  
currently this doesn't seem to work as I'd expect, so I'll look into  
that.
