Hello Sexy_n_17

This solutions is for laptops and I'm assuming your using a laptop because you have 2 colors of keys on keyboard White and Green.

There is a function key that you have to press and hold to use keys that have different colors letters or symbols. The is located near the CRTL key or ALT and says [Fn] press and hold than press the Squiggly key to make it work.
