So I'm not sure what the problem there is. In Indesign, this would mean being able to manipulate multiple sides of the same object frames. Example: holding alt (PC) should translate to holding option (Mac). To make things even more confusing, the issue appears to be program-specific.
I've tried the various keyboard options (1:1, translate, etc) with no joy. Also, holding spacebar should give me the hand grabber, but it does not. Example: (Going PC to Mac) pressing WIN+G should act as CMD+G and group objects in Indesign on the remote device, but nothing happens. The first is that not all of the keyboard shortcuts will translate over to the remote device.
