Hmm, I appear to have spread some confusion. To be clear: dtach implements just one of screen's many features, the ability to detach and resume a session. If you want all the other stuff that screen does, great! But if you don't then those other things can get in your way, and you might want to give dtach a try. (E.G., my own personal style is to launch multiple terminals from within emacs, so I don't need screen's m…

I like to run terminals in emacs as well, but every so often I get a segfault when the output is too long on a single line... I have screens doing the terminal handling now.

Screen's default command prefix C-a is not usable with emacs, which sounds like the problem you are having. I run screen with C-] prefix precisely for this reason.

IMO, if screen had...

(1) more sensible defaults: key bindings that didn't clash with emacs/bash and an always-visible status line

(2) a more distinctive, search-friendly name

...interest, discussion, and usage would be many multiples higher.

Anyone want to collaborate on a fork called 'zcreen'? :)

What is the windows key used for in bash? Could you just use that to begin screen commands?

Makes screen's commands prefix C-]. That really works very well with Emacs. Since that is command prefix of telnet, all other software avoids it.

screen is the best thing to happen to greenscreens since the buckling spring [1].

and FTW: try "nethack on" in your .screenrc [2]

Something like:

  hardstatus on
  hardstatus alwayslastline "%{rk}%H %{gk}%c %{yk}%M%d %{wk}%?%-Lw%?%{bw}%n*%f %t%?(%u)%?%{wk}%?%+Lw%?"

in ~/.screenrc gives an always-visible status line.

I use C-\ for the escape sequence. I'd add:

(3) Easier-to-use shift-pgup/pgdn equivalent

My .screenrc:

  escape ^\\
  hardstatus alwayslastline
  hardstatus string '%{= kG}[ %{G}%H %{g}][%= %{=kw}%?%-Lw%?%{r}(%{W}%n*%f %t%?(%u)%?%{r})%{w}%?%+Lw%?%?%= %{g}][%{B}%Y-%m-%d %{W}%c %{g}]'
  shell /bin/bash
  defflow off
  startup_message off
  defscrollback 1024

'defflow off' lets C-s work. The status line lists the current shells, computer name, time, and date.
