Ctrl-s should save the current state of my Text

Summary: It is a bit nerve-wracking to edit a large text block in a browser window. It would be very comforting if there was an easy way (probably ctrl-s) to do a quick save of at least that text, possibly the entire current state of the edit so far.
In the long run, this should become full autosave, but that can get a bit expensive if I don't design it right. For now, ctrl-s would be a good first step.
