I'm writing a few KB articles and am saying something along the lines of "Connect to abc and use credential xyz", then I'm creating a relation to password xyz on the article. I can't help but feel it would be great to Facebook/Twitter style type @, #, or similar, and then get a relation popup and be able to inline have a link. It would then be even better if clicking that inline link could have a popup with the credential/related information rather than navigating away (with the option to open the related link fully).
