Thanks. I thought that was QS, which these levers are also.
QS is Quickshift. It was a change to the FD shifter, reducing the amount of dead travel of the paddle. They also changed the cable pull and FD lever arm IIRC. It was available on many tiers worth of components, which is why it gets confused and tangled in the escape debacle.

Micron was intended to separate it from Escape which happened on the lower groups.
