Possibilities Jokes

A few days ago, we were trying to explain to a MS-DOS user
how the VI editor works. Here's what we come up with:
Vi is an editor with two distinguished modes:
In Edit mode you have all the capabilities of grandma's
typewriter right under your finger tips! You can make the
very same mistakes as you did with granny's typewriter
(and your possibilities to correct them are about the same).
That's why Vi was provided with a second mode, namely the
_Beep_ mode. On a vt100 terminal or compatible you can
get into Beep mode by pressing an arrow or escape function
key. In this powerful Beep mode even the more innocuous
keystroke will promptly produce a Beep sound. As an example,
arrows, return, blank spaces and most capital letters will
produce beeps in the most arbitrary places of the screen.
Just think about the whole world of possibilities that
this mode gives to you:
-Compose a monotonic symphony or rap while editing more...

Two possibilities exist: Either we are alone in the Universe or we are not. Both are equally terrifying. — Arthur C. Clarke
