 +===== Key =====
 +==== Format ====
 +key\\
 +key()
  
 +==== Description ====
 +Immediately returns an integer value corresponding to the currently pressed keyboard key.  If no key has been pressed since the last call to the **key** function then the number zero (0) will be returned. ​ This function returns the code for the key pressed not always the ASCII value of the character.
 +
 +==== Note ====
 +<​code>​
 +if key = 47 then print key
 +</​code>​
 +will not display the desired results, because it's calling key twice in succession, and will return different values each time.  This code will do what you want:
 +<​code>​
 +a = key
 +if a = 47 then print a
