keyboard.h

I'm trying to use the keyboard library however it seems I don't have the library. I just redownloaded the Arduino IDE, but it doesn't seem to come with the keyboard library. I found someone else's github that had it and downloaded that and included it, however I also don't have the HID.h library that the keyboard.h file includes. Any idea?

This keypad.h library? It's the one I use for 3x4, 4x4 keypads. http://playground.arduino.cc/Code/Keypad

Which Arduino are you using? The Keyboard reference page says:

These core libraries allow a 32u4 based boards or Due and Zero board to appear as a native Mouse and/or Keyboard to a connected computer.

By core libraries they are talking about the keyboard/mouse core libraries. So if you don't have one of the boards mentioned above those core libraries are not available.

Terminology gentlemen - keypad and keyboard are different devices. Recently a long discussion about keyboard turned out to be about musical instrument! And yes - there is a "native USB port" keyboard library , but ONLY for Due and some other offshoot of Arduino. But there are USB shields to run on Uno I presume. And on 1.6.6. IDE you have to use Libray Manager to install the USB Keyboard and Mouse libraries. . It sort of works but does not use interrupts - runs in loop
