When editing files, most of the time I go back to the shell using ^Z (editor go
in background), I do what's related to the file (try doas, restart httpd until
it works, etc..). And I use fg when I need to come back to the editor.
When playing with doas or sshd, I would recommend for doas to keep a root shell
opened in case you screw the file. And for sshd, when restarting it on a remote
machine, try to connect to it before exiting your current ssh session.
