When you press the read key to stop the playback/reading the book port
remembers where it was correct?
It also does this when the sleep timer activates or when you move to another
file etc.
The first thing the book port has to do before it remembers where it was
during these operations is to stop playing/reading so at this point the book
port is stopped.
When you press a key to tell the book port to do something if it is a
navigation command and the machine is playing it must stop what it is doing
in order to execute the command, even if it only stops playing/reading
briefly in order to move position and start playing again it must stop
playing in order to do this. So I would think the book port when it gets a
command it works out what the command is, if it is a command that requires
the book port to change its position in the file it stops playing, works out
where to start playing and then starts playing from the new location. So
you only need the book port to remember a position for undo when it is
stopped anyway.

There's a difference between keeping track _as you read_ and placing a marker _when you stop reading_. You may not agree, but the facts are the facts.

I do know the key I pressed and I have read the manual, I accidentally held
down the 2 key for too long. As for the book port constantly keeping track
of where it is I would assume it does that anyway because it can resume from
where it left off. I appreciate the bookport doesn't have huge processing
power but I am sure the position could be stored in say a couple of bytes,
It must have pointers to where it is in a file or how does it function? I
am sorry but I don't agree that it would introduce a huge processing
overhead, I remember the days when people wrote quite complex programs on 8
bit home computers with small amounts of memory. I was just putting it
forward as an idea as on my plextalk talking book machine I find undo useful
at times.
