How to type ' in Keyboard.h

Hello everyone,
When I use a Teensy 2.0 to simulate keypresses to the computer, I use Keyboard.h's function of Keyboard.press, eg.

Keyboard.press('a');

However, when I try to press the ' character, I have to do this

Keyboard.press(''');

Which the IDE doesn't recognize. What do I do? I tried using Keyboard.print like this

Keyboard.print("'");

But then I can't use shift along with it. I guess I could use a bunch of if statements to combine that with shift but there has to be an easier way.

Thanks!

Keyboard.press(39);

Keyboard.press('\'');

Did you want Shift-'? Wouldn't that be a double-quote?

  Keyboard.write('"');

Thanks so much! They work!
