>After some research, there is no support for the Esc key on such a device. The reason is that there is no use to it. However, some people use such device to remote access other devices, and then, an Esc key would be useful.
I bought a Logitech Bluetooth Easy Switch keyboard K811 for $99.00 and it has an ESC key and can handle 3 BT devices
in my case F1 turns on connection to Apple TV at home, F2 to my iPad, F3 to my iPhone
Great device!
