Thanks for these suggestions; you've picked up some cases where I wasn't
seeing the forest for the trees....

I really need to make some sort of "Preferences" menu that makes these
behaviors user-specified.  This is pretty straightforward.

This one is sort of annoying, and I don't exactly know why it does this
sometimes--I think it's part of the standard CView implemenation.  Anyhow,
I'll try to sort this out.

I should have done this a long time ago--thanks for pointing it out.  I put
it in this morning, and it took exactly one line of code to add in the
functionality for each key.  I've also mapped page up and page down to zoom
in and zoom out, as well as the 'home' key to 'zoom natural.'

This one could be a bit more subtle.  I'll have to think about how or if I
want do to this.  A better solution might be just to rethink the way that I
draw the screen to try to speed up the algorithm to the point where the
rendering of flux lines and density plots it isn't irritating for large
models.

Anyhow, thanks again.
