Aha! Evidently I *should* have known, but I *didn't* know, about the x and y keys. Sounds more and more familiar now, so I'm sure I saw some reference to it quite a while ago. Strangely, I did not stumble over it yesterday or today when looking at the code from the standpoint of making the proposed change. The toggle button would make it more obvious that the constraint options exist, and would make the operation easier on my laptop with the trackpad, but it is much less tempting now that you have reminded me of the keys. On the other hand, given that the basic functionality is already there with the keys, it would presumably be easier than I thought to add the button--although Darren doesn't like that interface design, and he may have a good point. Adding the key support to the zoom-to-rect definitely would help. > > I do think Darren's suggestion of making the toolbar more easily > extensible and configurable is a good one.

I'm glad Darren is interested; it is not something I would be likely to pursue myself. Too hard, with all the gui backends.
