So here's this totally rad idea.

You can't dingus-click with the keyboard, because you can't navigate the dingus
links or activate them. That's bad. I invoke the ghost of accessibility guilt.
Now you're listening! So:

 * provide a keyboard shortcut for dingus activation
 * if there's only a single dingus link visible, activate it
 * if there are multiple dingus links visible, pop up a simple dialogue with a
list of the dingus links, a cancel button (esc) and an activate button (enter,
but it needs a better name)

That way, if you're looking at a terminal with a few dingus links, you can hit
the keyboard combo, hit up or down to choose your link, and hit enter to follow
or escape to... escape.
