This is useful because you can exclude pages that would be otherwise be effected by a global style.\n\nAdd one or more exclusion entries for each style. An exclusion entry string contains a pattern that will match a web location (URL). This string may contain wildcards (\"*\") to match any portion of a URL, e.g. \"forum.*.com\" will exclude the forum sub-domains of all top level dot-com domains. Regular expressions are allowed, except `.` and `*` are altered, and are saved as a string so character classes must be doubly escaped (e.g. `\\\\w`).\n\nExcluded pages are automatically updated while typing; invalid entries will be removed on page reload!",
