Matches any single character except a newline character. Matches subexpression and remembers the match. If a part of a regular expression is enclosed in parentheses, that part of the regular expression is grouped together. If you need to use the matched substring within the same regular expression, you can retrieve it using the backreference num, where num 1.n. If you need to refer the matched substring somewhere outside the current regular expression (for example, in another regular expression as a replacement string), you can retrieve it using the dollar sign num, where num 1.n. If you need to include the parentheses characters into a subexpression, use ( or ). For example, zwood matches z or wood. For example, o2 does not match the o in Bob, but matches the first two os in foooood. For example, o2, does not match the o in Bob and matches all the os in foooood.

For example, A( means that WebStorm will search for A, but only if there is B before it. This is a pattern for negative lookbehind.
