Hi Tim,
As far as I understand it, BBLMKeywordPatterns are matched against
individual words composed of characters in the <Identifier and Keyword
Character Class> or <Identifier and Keyword Characters>.
As a consequence the ^ anchor in a BBLMKeywordPatterns is sort of
equivalent to \b and will always match at the start of a word.
Start of line for an individual word doesn't make much sense.
(*Please Rich or Patrick, correct me if I am wrong*)
You could kind of achieve what you are looking for by including the '%' and
':' characters in the <Identifier and Keyword Character Class> and matching
in the BBLMKeywordPatterns with:
keyword:
and
%keywordtwo:
Watch out though that those sequences might be present in some other
unwanted positions in the text, for example at the end of a line before a
bullet list.
Another solution could be to use the <Keyword Pattern> which is matched
against the text of the document and thus can detect ^ anchors at the start
of lines.
