stop_clock: All it did was stop the real time clock of the system from counting up when you pressed the alt key and started it again on a 2nd press. However, this was enough to stop the timer of a typing speed program we used in high school. Magically, I was a VERY fast typist. :-)
stay_on: When you pressed a certain key sequence it would start the floppy drive motor and a 2nd press would turn it off. The goal was to speed up floppy accesses by not needing to spin up the motor all the time. Unfortunately, I got up one day to find my floppy drive motor dead. I suspect I forgot to turn off the motor (there was no idle timeout...I was a kid, never even crossed my mind!)
