The point of using message keys in this way is that you know how far
back to go before you stop looking. The SNDMSG sets a sort of
'checkpoint' that says 'The process I am interested in begins here so
don't look for messages before this point.'

I guess you meant SNDPGMMSG?

Yes. I think of all of the SNDxxxMSG commands as synonyms. I ought to
be more careful.

What you are describing sounds like what
Barbara was talking about, though she didn't specifically mention
message keys. Presumably there are other ways to recognize your own
checkpoints (she called them "markers"; the term that first pops into
my mind is "sentinels") besides the message key.

Yes, it's exactly what Barbara is writing about.
Marker and sentinel are good words to describe the idea.
