As an editor who uses wiki markup and often edits pages with a lot of templates, I would like to be able to (modifier +) click on a {{template}} (e.g. {{support}}) to quickly go to that template's page (e.g. [[Template:Support]]).
This would speed up editing complex pages with lots of templates, as it would save me having to copy/paste the template name.
I'd previously written a user script (linkThings.js) which adds this functionality via ctrl + clicking on any {{template}} to both the visual source editor and the CodeMirror editor.
