Does anyone know if it's possible to change the softkeys available for notifications? I really like the notification pop-up that tells you what the email or SMS is about without having to open the messaging app, but the only options with email are to dismiss the notification or to open messaging and view the message.

I wish I could delete the email or mark as read from the notification. Preferably the right softkey would offer a menu like the SMS notification does.

Any ideas?
