"Gem Activated" secret editor button, what is it?

Hey, i been making maps for over 3 years now and its the first time that i realize that the editor at the end of both horizontal and vertical scroll bars has a button, hehehe ... i clicked it by accident, and an inscription apeared in the screen "Gem Activated" it deactivates if you click twise. I can't belive i never seen it before, i hope thats not the answer to all the ridles, LOL :P
Well anyway, what is it?

Thanks

PS: not even the world editor tutorial speaks of it

When on, units that you delete will play their death animations and death sound, instead of just disappearing. Click it really fast for another surprise.

It will cause units to play their sounds sometimes when you click on them, they will play death animation when removed, and if you click the gem a bunch of times it will play angry sounds.

Edit: Too slow. Guess I ruined the surprise :).

Quick! Edit away the spoiler!

wow so as i though is useless, at least to me i dont see what use coud i give to it, thank you very much i would never figured it was for that

its just a easteregg

it's a ghost rising from the depths of Diablo 2... ):

I was told if you click it exactly 255 times, you unlock bonus maps.
It never worked for me. =(

Its 8191 (since this is when the map shits itself with arrays and saving)

yeah and ppl have told me they used a sniper bb gun and if you go gamerevolution somewhere between 10-30% of the stuff on there is ppl trying to look cool.

"yeah and ppl have told me they used a sniper bb gun"

wat?
A) lol... unrelated a bit
B) there is such ting, so i see no problem, are u saying that its real? (the 8191 clicks)

I'm gonna try that 8191 clicks right now.

EDIT: It plays a random "Pissed" sound when you click it repeatedly. Just before the screen fills up with "Gem Activated/Deactivated" it plays a sound.

u can use gem activates to takescreenshot of a destroyed city without trigger ^^
