[Elecraft] Macro generation

[N6FB at aol.com]

I am totally confused on generating a macro, and the more I read on  the 
Utility Help page, the more confused I get.  Evidently, there is  somewhere a 
list of what are called "K3 Commands" which when strung together  form a 
custom macro.  But where is the list of such  commands?
 
Can anyone who is more familiar with this than I am give me  a  step by 
step tutorial on how to create and implant in my K3 at location  PF1, a macro 
that will turn on the APF and the RIT??? ( I am assuming this macro  will 
turn off if the PF1 is pushed a second time---or is that a bad  assumption?)
 
Gee it is tough to have spent your whole career in aerospace  electronics 
and find yourself completely out-of-date after being retired for 17  years.
