Eliminate control key for arrows?
v. 3.0 on a Mac has the behavior that arrow keys have the same effect as CMD+arrow keys on the admittedly very simple PDFs that I use (no sections). For simplicity's sake then, why not eliminate the CMD behavior or at least don't show it in the tips? I don't think anyone expects it since the arrow keys by themselves work for navigation in all the other presentation apps that I can think of.
(The "q" for quit behavior is the one that should require the CMD key.)
