Title: TextPad equivalent

(\<[[:word:]]+)[[:space:]]+\1\>
TextPad regex supports POSIX character classes but not Perl Compatible Regular Expression (PCRE) character types. So "\b", "\w", and "\s" must be replaced with their class counterparts. Also, TextPad recognizes a beginning word boundary "\<" and an ending word boundary "\>".
NOTE: Make sure to enable "Use POSIX regular expression syntax" in Configure -> Preferences -> Editor to minimize reliance on additional escape characters in your regex.
