I remember how impressed with myself I was when I learned to simply follow the instructions that said "press ^] to escape" when using the King County Library System's telnet menu system. That is to say, the library computer system presented you a menu with a very small number of telnet destination options you chose by number. But if you chose one, and hit the escape sequence, it would gasp escape, and then you just had to know the 'open' command to telnet ANYWHERE IN THE WORLD. You could also access the library system remotely, but I can't remember how or why this mattered -- maybe it was from another menu system that didn't allow escapes, or maybe there was a dialup option, or... something. In any event, you could hop from one place, into KCLS, use the menu to telnet, break out of the connection, and open a connection to another place. It was like magic.
