Using Processing 0123. Not much more to say than what's in the summary.
This if-statement will always be false.

<code>
if ( key == CODED && keyCode == ENTER )
{
// do something
}
</code>

that's just how java does it. ENTER is not a CODED key, presumably because
ENTER has an actual ascii value (10). you'd have to check sun's javadoc for
their logic.
