113 is the ascii code for 'q'.

316 is the keyboard scan code for F2.

Two different formats.. Or am I mistaken?

wait_key() (which is actually a modified version of get_key() ),
returns the ascii code for displayable keys, for others, like the arrow 
keys, function keys, and home keys, the scan code is returned.
