Using cec-tray I can see that there are a lot of commands, but I don't know how to use it to send CEC commands from laptop to TV. In CEC tester tab I can power on device, put device in standby and get device information. But I don't know how can I send commands like channel up, channel down, volume up, volume down,... Another command I'm interested in is select A/V input, but it is disabled.
I didn't find any user manual or help document. Can anyone help me?
