Type 10 (you don't have to press ENTER).
Press and hold down ON.
Press the top left key exactly twice while still holding ON down.
Release ON (see 0E10 in the display).
Press 1/X --> crash

OK, I'm curious, how you can figured out this feature?!?
This is 6 keystroke, on 12C has 39 keys, this is (39^4) × (39×38^2) = 1.30E+11 possible keystroke (and I cannot try to think the order is important or not or I must to multiple it something binomial stuff).

So, you just sit at the table and try to push keys and you believe it will happen something?
