How do I detach a screen session from a terminal?
Ctrl+a followed by d. Note the lower case. The [screen manpage] has a long list of these shortcuts under "DEFAULT KEY BINDINGS".
To list your sessions, run:
screen -list
You can run any command under screen command like:
screen myscript.sh
Then press Ctrl+a (release) and then d to detach the process/screen (so it'll continue to run).
To resume detached process, use:
screen -r
If you have multiple, then add the session number after that.
You can also re-attach to already Attached screen by screen -x. Useful to investigate why it's attached, share terminal with someone or to watch/check somebody what they're doing.
For more help, either run man screen or within the screen press Ctrl+a, release and then hit ? to see more shortcuts.

It's important the note the case of the letters as uppercase and lowercase will do different functions.
