Well, I was proposing more or less that but with ^ because of the
precedent of the two existing box_above/box_below operator names.
However, I'm quite happy to adopt your names, since that's probably
a more widely used precedent. Sold, unless there are objections.
(BTW, it does look a bit odd that the "|" moves around in your names.
But I don't dislike it enough to not follow the precedent.)

Agreed, I'll use your strategy number assignments too.
