[HELP] Keyboard commands ar not working in Arduino IDE

Hello everybody!

I having problems with my Arduino IDE, I’m trying to get my Arduino Leonardo to act as a HID keyboard but the Keyboard.begin and all other keyboard commands aren’t working.

Does anybody know how to help me out here?
Thanks in advanced!

Well, does it? If not, add it. If so, please post your sketch using code tags(</> button on the toolbar).
