[Elecraft] Memory Keyer - Dumb Question

[Shane Justice]

O.K.- Here's the dumb question of the decade- I have been reading  
through the manual, and I can't find explicit information about CW  
memory keying. First, I am assuming one needs the DVR option to make  
the memory keyer function work. Is this true? Second, how does one  
store what one wants in the memory? Is this only entered through the  
computer interface, or can one "send" morse code in some recording  
mode? ( I hereby apologize if I'm asking a dumb noob question, the  
answer to which is RTFM)

Thank you, in advance, to any kind soul setting me straight!!
