Fernando,

An Easter Egg, in this reference, just refers to a surprise that you will find by pressing certain key combinations or clicking some combination of links/areas. There are supposedly numerous Easter Eggs hidden in Microsoft's products. This one sounds particulary interesting. I had not previously heard of any in FoxPro/VFP. Unfortunately, I do not go back far enough to see if this is really in FoxPro 1.1

Good luck with your search and thank for all of your interesting documentation! I've greatly enjoyed reading it and all the updates!
