Low-E-F connection

What: Low-E-key (R-t) automatically closes low-F-key (R-4f)

Slurs from low-E (and all lower notes) up to Ab/G# are facilitated because low-E can be fingered in the R-hand:
/ E ● ● ● (rather than: / E ● ● ● F) leaving R-4f free to press the Ab-key without having to slide from the F-key.

One cannot mute low-G with the E-key.
