A few years ago I learned how to suspend an ssh terminal connection (like ctrl-z for a regular app). I forgot how to do that or even how I would look it up.
Anyone know?
The fresh carriage return is key. Took me awhile to understand it needed to be done on an unblemished input line.
I'm pretty sure this stacks for nested ssh sessions too. ~ current session, ~~ for it's parent, and so on. I might have this reversed.
