where's the any key

In Russia when English computers were starting to be introduced, some things weren't translated, like "press any key to continue." Because English was the second language, the "any key" was assumed to be an actual key. As a result, sysadmins became known as "anykeyers" because they'd come and press the "any key" that eluded users.

It's the same as you power button. You just need to hold it down.
