For short hard efforts, I toggle between ERG and Resistance (on TR), where ERG is for the rest period and Resistance for the hard part and is pre-set - no gear changes needed.
It helps that I've got toggle and resistance up/down keys out front.
Amazing. Is that just acting as a regular (but very small) USB keyboard into a computer? I was thinking of something like this as a lockdown project, but was looking more at pre-built wireless devices. But then they are designed around controlling media players etc.
