=== Definition ===
----
'''key()''' is a [[function]] that needs a [[constant]] or a [[variable]] with the scancode
or the scancode itself for the key you want to check.
The [[variable]] [[ascii]] shows the scancode of the key currently pressed.
This [[function]] returns 0 or [[false]] if the key is not pressed, 1 or [[true]] if it is pressed.

The [[constant]]s for the keys commonly start with _ + the key.
So if you want to check for the letter 'a' to be pressed, you would pass _a to key().

You can find a list of the constants and keycodes here.

=== Example ===
<pre>
program input_test;
begin
set_mode(320,240,16);
set_fps(60,0);

while( !key(_esc) )

delete_text();

if( key(_left) && !key(_right) )
write(0,160,120,4, "LEFT");
end;

if( key(_right) && !key(_left) )
write(0,160,120,4, "RIGHT");
end;

frame;
end;

exit();
end;
</pre>
This will output the words LEFT or RIGHT according to the keys you press,
or it will quit the program once ESCAPE is pressed.
