If you're just getting starting with a screen multiplexer, I'd suggest
starting with tmux. My understanding is that GNU screen has
effectively been abandoned.
I used GNU screen for at least 10 years, and recently switched to
tmux. As someone else said, in GNU screen, if you want to send ctrl-a
to your application (e.g. shell or emacs), you can do ctrl-a followed
by a "naked" a. I found this becomes so second nature, for the rare
time I'm not in screen/tmux, I habitually do the Ctrl-a a sequence!
tmux's default "action" sequence is Ctrl-b. Even without my history
of Ctrl-a muscle memory, I think I'd find Ctrl-b awkward. I briefly
tried to get used to it so I could live without a custom tmux config
file, but just couldn't do it. So, here's my small ~/.tmux.conf file:
# remap Ctrl-b to Ctrl-a (to emulate behavior of GNU screen)
unbind C-b
set -g prefix C-a
bind C-a send-prefix
# use vi-like keybindings
set-window-option -g mode-keys vi
# emulate GNU screen's Ctrl-a a sequence to jump to beginning of
# line
bind a send-prefix
