Keyboard.releaseAll() not working on teensy
I am not sure it is an Arduino IDE issue but it seems to be so.

Keyboard.releaseAll() is recognized but gives an error:

Buttons.cpp.o: In function `loop':
C:\Program Files (x86)\Arduino/Buttons.ino:91: undefined reference to `usb_keyboard_class::releaseAll()'
collect2.exe: error: ld returned 1 exit status

I don't need help. I will work around this. But why?

void setup( void ) { }

void loop( void )
{
  Keyboard.releaseAll();
}

Works fine for me.

Doubt it.

Here is my project. Everything seems to be right.

Teensyduino was downloaded and installed last week.

Than it may be a Teensy 3.0 issue...
I have Teensy 3.0. But why? This function stands far away from hardware.

When I compile this program for teensy 2 there is no error. It is a teensyduino error.
