When the “circle” popped off my Dexcom receiver last week, a thread in the discussion on that post highlighted the mystery of the “right button.”  As in, what the hell does it do?

And it’s taken me until today to realize that I use the right button all the time, or at least have the option to use the right button:  when calibrating the sensor.

If I enter the wrong blood sugar number, the right button (affectionately known as “Easterly”) allows me to cancel that calibration and start over.

See, Harry?  It does do something!!!
