+--Arguments--
+
+The @condition@, @default_expand@ and @combine@ functions will be called for each potential keyword match in the input.

+Keyword matching is case insensitive, to get case sensitive matching use a @condition@ that check for the @correct case@:

+In prior MSE versions matching was always case sensitive.
