Yes I have tried many different keys both in key bindings and in macros. Everything works fine for anything but switching the stanza action bar. I am using the latest beta from the ones that are available, but it has never worked on any of the versions I have been on. I have both imac and airbook running the latest OS. It works fine on Windows but not on Apple. I use the full Apple keyboard on both machines, with the numeric keypad. Again, all macros and key bindings work great on anything but the action bar.
