On the K3, it would be really helpful to have an option to reconfigure 
that button on the K3 as "tap = APF" so that we don't have to lose "hold 
= DUAL PB".

"Tap = APF" would also bring the K3 into line with the KX3.

Obviously APF and DUAL PB cannot both be selected at the same time, but 
it would still be helpful to have either one available QUICKLY on the 
same button.

No XFIL users would be inconvenienced by making this a configuration 
option.
