My personal favorite would be "P", but that is taken already.  From
there I'd use either "j" (for jump), "M-p" (because it has a "p"), or
"."  (because it is a point).  If you have any better ideas, please let
me know, I'm completely open here.  I attached the list of used and free
current edebug bindings, sorted by keys.

When we extend the notion of "previous value" to "what has been
single-stepped through OR what has been evaluated with `e' or `C-x C-e'"
we can have that as well.  So you press "C-x C-e", get some buffer
position back, and then press "j" (or whatever) to bounce to that
value.

Only the user interface is potentially slightly more confusing, then.
I attached a revised patch implementing that.


Please let me know your choice of key and patch (v1 from
https://debbugs.gnu.org/cgi/bugreport.cgi?bug=79288#5 or v2 from this
message), and I will continue on that route.

Thanks!
