I don't know if I understand You

. I will write here what are the possibilities of operating channel 3:
- use trim (steering/throttle/ch3/dualrate), set required step (1...200) and use trim buttons to move channel value "trim step" left or right (value is in range -100...100). It is also possible to use that rotate dial to change value when value is showed at display. It is also possible to define what long-press of trim button will do. There are 2 possibilities, one will reset channel to centre and second will set value to full left/right, depending on pressed button.
- use trim and set it to MOMentary. Then when nothing is pressed, channel value is at centre. While holding one trim button, channel value is set to full left/right depending on holded button.
- use key (for example CH3 button) as switch. Each press of button will switch value from left to right or back (this is what was at original firmware).
- use key as MOMentary. Channel value is changed to opposite side only while holding that key. And to this code I added special handling for those who will modify CH3 button to 3-pos switch, so there will be 3 positions left/centre/right. But I didn't modified my radio so this is not tested yet.
- use trim and key. Use trim buttons to set channel value to left/right (set step to 200 to have always full left/right) and use key (eg. CH3 button) to set channel value to centre.
This all is assignable at radio in "key mapping" where You assign functions to trims/keys.
