@b0rk one practical use for it is if your terminal becomes wonky. For example, characters not echoing and enter key not actually working. I've seen this when interrupting an ssh connection before being fully established. You can type 'stty sane' followed by a Ctrl+J and get it back. I do this at least four to five times a year.
@tildetodd “reset” is easier to remember & also fixes a borked terminal
