Requested feature overview description.
(left-clicking on a autocomplete menu item adds the selected tag to the search/taglist, I do not want this to be changed.)
if you mouse over any of the items that pop up in the autocomplete menu you'll see that the associated URL is "/post?tags=<tag>" when middle-clicking (or right-clicking and open link or whatever) this link will open. I think it might be more useful if this link was instead changed to be "/wiki_pages/show_or_new?title=<tag>".
Why would it be useful?
this is kind of a niche feature that I can't imagine gets used that often, but for me at least, the only time I've ever used it was when I was curious about a tag that I'd never seen used before or when I'm tagging and see a tag that I've never added to a post. generally in situations like this a link to a wikipage contains more helpful and concise information than a full search page.
it'd also be nice to have a quick way to get to a wiki page for a tag that's not shown in the side-bar
What part(s) of the site page(s) are affected?
tag searches, editing post tags, tagging to new posts
