[texworks] Regex challenges

I'm trying to improve my set of regex expressions for writing DTX files.
There are a couple I'm stuck on: suggestions welcome.
1) The standard pattern for matching control sequences is
\\(?:[A-Za-z@]+|.) This behaves OK unless I follow the sequence by a '
character. If I do, anything following the last @ is not coloured but
stays black. If I extend the match sequence for LaTeX3-like code
\\(?:[A-Za-z at _:]+|.) then anything after the last non-letter (@, :, _)
is not coloured. Is my expression defective or is this the matching system?
2) In a DTX, comments in the explanation part start ^^A. This is easy to
match with \^\^A, but that matches even in the code blocks. Ideally,
- If the line start %, comment = ^^A
- If the line starts without %, comment = %
but only colouring from the start of the comment, not the start of the
line. Is this doable at all?
Thanks in advance for any clues.
