Otis, you are running into complex issues related to not having a toolbar that would let you switch between modes of operation, I think. You  might want to try to improvise one -- adding a background image, and when it is clicked, have the binding change. Or add your own toolbar outside of the applet. I think what you are asking for (from the user) is way more than is necessary. If you are thinking "ioS" think "simple interface".

Bob,

The ability to bind double represented an approach to modified dragging on the iPad that provided the equivalent of key modified dragging. With the new iPad OS, this is no longer an option. The new iPad OS introduced complex gestures that obscure the double tap. I don't think this situation is going to change. Nothing is broken here. The iPad is simply no longer compatible with double click drag.

Would it be possible to create a Jmol on/off property that when set would be the equivalent of a pressed alt key? Actually, on/off equivalents for alt and shift would be ideal. Again, my main concern here is modified dragging.

I could handle this with global JavaScript variables inside a call-back, but modified dragging on touch devices might be of general interest to application developers - hence this user list query about building this into Jmol.
