You have fg, bg kill %NUMBER comands, that is all shell. Actually C-z
is expectation coming from shell. I did not know that C-z has to be
implemented in Emacs or other software. My opinion was that C-z is
shell control of other software, regardless if that other software
have implemented various key bindings I was thinking shell is in
charge and in authority over programs running in the shell.

So C-z is my expectation to work always. Maybe is not so in reality.

This would invoke job #1 to come into foreground:

$ fg 1

This would invoke job #2 to come into foreground:

$ fg 2

So you could have multiple Emacs sessions or multiple editors in the
same shell and switching between them that way. That is not same as
screen/tmux as suspending a job does not continue execution of the
job.
