[Elecraft] KX3 Macros for Split Operation

[Buck k4ia]

I have written a couple of Macros for the KX3 but need some help

This one will put the rig into Split, Xmt on VFOB, VFOB up 2, RIT=0, 
XIT=0, Turn on Dual Watch, Clear the Menu off the screen

SWT25;SWT25;FT1;UPB5;RT0;XT0;MN140;MP016;SWH09;

This one will restore to regular operation (undoing above)

SWT25;SWT25;FT0;UPB0;MN140;MP000;SWH09;

Question #1: How do I make the OFS/B knob set to activate the B 
function?  If it is on OFS, it will control VFO A and I want it to 
control VFO B so I can tune to hear the other side of the pileup. 
Nothing I do seems to alter whatever it was set to when I started.

Question #2:   I can't find a CONFIG:MACRO x menu item on the KX3 to 
assign my masterpieces to a button.  How do I do that?  It looks like I 
can assign a simple menu item to PF1/2 (page 19 of Operator Manual) but 
I can't find anything about Macros.

Question #3:  Other than PF1 and PF2, how do I assign macros to other 
keys?  The K3 had the M1 - M4 keys but they are not on the KX3.
