How to use media keys with a keyword

[Zlistyk]

I want to create a workflow where I can use the media keys with a certain keyword. For example my keyword input is 'ne' and when I type 'ne' in alfred, it presses the 'next' media key on the keyboard. How do I do it?

 

Thank you for any help.

What are "media keys"?
 
At any rate, the way to trigger keypresses that aren't characters is: 

tell application "System Events" to key code XX

 where "XX" is the numerical code of the key.
