+The Keys library helps you with Input API to get key code by key's names, or identify a key code.
+
+Notes on compatibility with ComputerCraft: although this library is ComputerCraft-compliant, but Numpads are \emph{not} supported whatsoever. \textit{Come on, it's not like everyone has or likes numpad on their keyboard.}
