The event is executed
when the corresponding key key is pressed (see key mapping).
Functions can be assigned most keys. The scancode of the key is passed as
parameter to the function. Scancodes are unique numbers in the range 0..127 assigned
to each key; they are listed in the table in the following chapter.
Example:
function quit() { sys_exit(NULL); }
...
on_f1 = quit; // assign quit() to key [F1]
