How can I dismiss puplet messages with a keyboard shortcut?

Question

puplet is forever reminding me when it's time to run "yum update", which is fine, but I'm forced to click the little x to dismiss the dialog. Is there a keyboard shortcut or command that can dismiss it for me? I'm running GNOME 2.16.0 on RHEL5. Here's a screenshot:

Adding a timeout means I don't have to dismiss the puplet message:
