Early versions of Pick did not natively have a way to reference the Master 
Dictionary at all.  That is, you could not open the master dictionary as a file 
because there was no reference to it, to use as the text handle against an OPEN.

This is why the MD itself had a Q pointer called MD, which just had a Q in the 
first field and nothing else in it.

Now having an item in the master dictionary to point at itself, you can

OPEN "MD" TO F.MD

Q pointers do not need anything in the second field.
If you only have a Q in the first field and then a name in the *third* field, 
then it assume you are making a "short" link (quick link) to a file with a long 
name.
