Arducopter Quad T8SG V2 TX + FrskyX and emulator

Good Day to All.

First post and a couple of questions already.
I am planning to fly an S500 quad with pixhawk firmware and FrSky X8R receiver (FrskyX protocol). The TX will be a T8SG V2.
I have made a model for the quad, mostly by copying and modifying the APM model as it was posted on the wiki link

www.deviationtx.com/wiki/model_config/ap...spektrum_dsm2_8ch_rx .

I do not have a physical access to the controller as i am way far from home (China, and i am from Greece -a ShipCaptain that got stuck
abroad due to Corona ).

Anyways, i wanted to test the validity of the model in order to have it ready as soon as i return home as i have an anxious
young boy waiting to do things with his dad.
I downloaded the T8SG emulator from the downloads ( build: deviation-emu_t8sg_v2-v5.0.0-48d7be1 )
but none of the SW A/B/C...H register or get activated by any of the keys from the computer keyboard and Chapter 12 of the manual provides
bindings for the Devo series controllers only. In addition i have noticed that even though on the hardware.ini on the emu filesystem the parameter
" nostock " is active i still can see and activate the FMODE and HOLD toggles only, which from what i understand are not valid T8SG switches.
So far for the long prologue, the questions now are :

- Below i am quoting the model on the message, if someone has the kindness to check it and advise me if it is OK and if not, what to change.
The target is six flight modes on SW D/B/G and Throttle hold.
- If it is not OK please advise me the mistakes i did as i am a first-timer on deviationtx.
- Can someone advise if there is any particular setup/change/modification i need to do in order to activate the switches on the emulator and
what are the actual computer keybindings to activate the the SW A through H.

Thanking You all in advance.
