What about link text? You could type it in like wiki:
[http://example.com|this is an example].

When I wrote my Simple Linkifier I tried to make it automatically fill in the link text from the <title> tag of the page linked to, to save having to copy it between tabs. But I couldn't: the browser Same Origin Policy I referred to doesn't let one page pull data from another, unrelated, page. For obvious reasons. But you could do it in a separate program.
