Thank you for your reply. I realise the question I should have asked is "Is there a keyboard command for ATC "Readback Transmission" ?" So instead of keep moving the mouse to keep clickiing "Readback Transmission" after every message all I have to do is press a joystick button.
I have found a command for "Open ATC" ( which is Return), is there one for Readback Transmission?
Thank you,
