When I construct a link like this, it would be very useful to have it display the associated page's title as alt text:

[[[ my-page ]]]

Wikipedia does this - http://en.wikipedia.org/wiki/Main_Page - just hover the mouse over any link on that page to see the associated page's title appear in a hovertip.

Yes, I can do syntax like this…

[[[ my-page | ]]]

… and the page title will appear on the page automatically. However, in at least one use case on my site this isn't what I want, as I'd prefer the link text to remain as the page's unix name, with the title as a hovertip (as mentioned above).
