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 your thesis!
-Send messages in morse code to the secretary next door!
-Keep yourself awake with the clear sound of the Beep tone!
The possibilities are up to you!
