Yes, it does exist. In the <a> tag, there is an attribute called title which displays it like the alt attribute on an image. Try running your mouse over

This

and on most browsers this will work. Plus, there is no Javascript or any special stuff involved.

I agree, though, that links should have a little caption on it like the title that used to show up in the [id://XXXXX] thing.

Sort of like what happens in those Ulitimate Bulletin Board scripts, no?

UPDATE: I just noticed that vroom doesn't allow this to be used on-site so there is no example :(
