any key
The phrase "any key," which frequently appears in the direction to computer users to "Press any key," is reportedly a source of confusion to many. At least one help desk person reports that users sometimes examine that direction more carefully than intended and call to find out whether "any key" includes such keys as the tilde, the Break key, and the key on many keyboards that shows the Microsoft Windows logo.
"Any key" does indeed include those keys.
