I only want this to work "ttk" at the start. I know that ^ means the
start but I am not sure how to add that (I did try just adding it) to
make the regex start with "ttk".
Just put it at the beginning:
"^ttk..."
just as you would use the dollar-sign at the end to anchor something to
the end of the line:
"regexp$"
-tim
Similarly, to allow it as long as it is the first non-whitespace
characters, add "zero or more whitespace" between ^ and ttk :
"^\s*ttk..."
See ":help pattern.txt" for more info on Vim regular expressions (and
dont forget the .txt extension, or you'll be brought to a formal syntax
definition instead of to the table of contents of the helpfile).
Note that $^ in the middle of a pattern usually matches dollar followed
by caret, not a linebreak. ( \n matches a linebreak IIUC; but in
substitute you must use :s/\n/\r/ to replace a linebreak by itself.)
Best regards,
Tony.
