In some cases the shortcut link syntax is not enough and more complex links are desired. For example given the issue 12345 on project CMS of an external ticketing system the URL could be something like

http://boss.com/tickets?project=CMS&issue=12345

This cannot be mapped using the current shortcut format but what if shortcut links supported regular expressions?

Assuming the regex shortcut link of CMS-12345@Boss the regex

^(\w+)-(\w)$

... could be matched to the URL template

http://boss.com/tickets?project\1&issue=\2

... which would then produce the correct URL.

Using regular expressions in a Shortcut Link would be optional and the existing simpler syntax should still be supported.
