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

if key = 47 then print key

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:

a = key
if a = 47 then print a
