Continue a current job in the background and detach it from current terminal

You can stop the running command using , but that may produce undesirable side-effects. suspends the job, and (assuming you have no other jobs running in the background) %1 resumes it. Appending & tells it to run in the background.
You now have a job running concurrently with your terminal. Note this will still print any output to the same terminal you're working on.
Tested on zsh and bash.
