Something like OmniGraffle's "Jump Elsewhere" functionality would be really great.

After a day spent learning Applescript, I've come up with a pair of scripts that will (I hope) be good enough for what I need -- one for copying the id of the target row into the note field of the source row, and one to read the note field of the source row, hoist the target's parent, and select the target. Still, there ought to be a more elegant way...
