Hmmm, well, I don't believe I've ever received a single comment on the
"camera" moving keys before. Plus I've never been quite happy with
the way they affect the opengl view matrix (but not the ldraw matrix).
So I suppose I could just redefine them for the next release.
How about this?
Arrows keys move the current part LEDIT mode, the model in LDRAW mode.
Shifted Arrow keys spin the model by 1 degree.
Alt and Arrow keys spin the model by 5 degrees.
Shift, Alt, and Arrows spin the model by 45 degrees.
Ctrl Arrow key combinations are reserved for manipulating the camera.
Forget about the function keys. I'll reserve them for other stuff.
