Yeah, I *really* broke “Don’t Write Angry”! Many thanks for not responding in kind—I rather suspect that you’re a better person than I, especially since I now notice that you wrote much of the code I was trashing. I don’t think I could’ve been quite so level headed in the face of a similar onslaught…
I apologise both to you, Paul, and to anyone else I may have offended.

If the keyboard was arranged in a grid, then it would be “trivial” (for a given value of trivial) to parse the <position>/<area> elements in the XML and calculate which widget is above, below, etc. the currently focused widget. The supplied keyboard.xml staggers the keys, which would presumably make the calculations more complex.
Part of the problem I’m facing is that even though the <LANG>.xml files all map to the same layout as defined in keyboard.xml, the <move> elements are still in <LANG>.xml.

Well there’s the <focusorder> “attribute”, but that’s one dimensional—as far as I can tell, a MythUI window itself doesn’t support two dimensional widget navigation *at all*. RIGHT and DOWN both move to the next widget in <focusorder> order, falling back to the order they are defined in the XML.

There are *many* more important things, I know—there always are. However, since I don’t know C++, hopefully my work on this only takes time away from my own projects. Well, except when I post a borderline abusive message and you take the time to write such a graceful reply.
