pass

pass functionName
pass messageName

The pass keyword ends execution of the current handler and sends the entire message that initiated execution of the handler to the next object in the message-passing order.

(Ordinarily, once a message is handled, it does not continue along the message- passing order.)

In general, a stack should pass any system messages that it handles so that other stacks later in the message-passing order also get a chance to handle the message.

For example, a mouseWithin handler in your Home stack won't ever run if you also have a mouseWithin handler without a pass statement in a stack before Home in the message-passing path.
