The map-snip% already uses the mouse wheel for zooming, but DrRacket binds those events to scroll the REPL window up and down, so the snip never receives these events -- this is the reason why I added the "up" and "down" keys. The REPL example is just a side benefit of using snips for the map object, but for my own use, I put the map-snip% in a pasteboard% which I fully control, so the keyboard navigation is not an issue. Perhaps I'll add some keymap% bindings for more general control of the map snip, so that users can bind whatever keys they prefer... > > A package containing a database of the positions of the major cities and > countries would be nice too :) > A general facility able to resolve location names to GPS coordinates would be a lot of work, and I don't have time for such a thing.
