'.
(idlwave-find-key KEY-RE &optional DIR NOMARK LIMIT)
Move to next match of the regular expression KEY-RE.
Matches inside comments or string constants will be ignored.
If DIR is negative, the search will be backwards.
At a successful match, the mark is pushed unless NOMARK is non-nil.
Searches are limited to LIMIT.
Searches are case-insensitive and use a special syntax table which
treats `$' and `_' as word characters.
Return value is the beginning of the match or (in case of failure) nil.
