no job control in this shell (was: Proposal: "C-z <letter>" reserved for users)

Emacs...)

Are you a bash user? The references you posted kind of suggested zsh to me,
but it wasn't clear. If you are using bash, does executing

set -m

allow you to use job control (fg and bg)? When I searched for "no job
control in this shell," that was the suggestion. If I execute

set +m
emacs -nw

I am unable to suspend emacs using C-z, so I suspect that might be what's
going on.

>From the documentation for set -m in the bash man page:

              -m      Monitor  mode.   Job control is enabled.  This option
is
                      on by default for interactive  shells  on  systems
 that
                      support  it  (see JOB CONTROL above).  All processes
run
                      in a separate process group.  When a background job
com‐
                      pletes, the shell prints a line containing its exit
sta‐
                      tus.
