Readline shortcuts: Ctrl-s and XOFF

And another contribution to my list of Readline keyboard shortcuts. This time it's a note by João Matos, pointing me to problems with the Ctrl-s shortcut. (It acts as a flow control character that pauses transmission on some terminals.) Read More »

I regularly need to remove domains from the DB and I don't want stale or incorrect references as a result. Read More »
