[Elecraft] New K1 functions shown on latest K1 Quick Reference

[Mike]

I notice on the K1 Quick Reference available at the Builder's Resources
section of the Elecraft site, there are some new functions shown under
the INP menu item.  The list there contains reference to ADn and ADr
functions, accessible by holding the DISPLAY button.  My K1, with rev.
1.09E MCU firmware, does not appear to have these functions.

These functions do not show up on any K1 manual through rev. F, even on
the almost identical Quick Reference that has always been the last page
of the manual.

Does anyone have an inside story on these new functions?  I sent
Elecraft Support this question at 0830 PDT this morning but I haven't
received an official reply yet, so I thought I'd check the list for
info.
