Holy $DEITY!

On the first glance, that looked like a belated April joke. But since one of the comments referred to Wikipedia, I got curious - and it really seems to be true!

Other thoughts were: Hmmm, how could anything with human proportions press all these keys at the same time? And is it really all uppercase?

It's NOT. Use lowercase letters. And for tips on how to make keys like Alt or SysReq sticky, go and follow the links mentioned in Wikipedia, or read http://aplawrence.com/Words2005/2005_04_13.html or type "echo 1 > sysrq-sticky".

It really is some time ago that I joined the force and read the source, as it seems...
Thank you all. Saved me already.
