Keyboard navigation to notifcation balloons in the top panel

[Willie Walker]

Hi All:

Every once in a while, I will notice a notification balloon appear in
the top panel - these balloons are for things such as the
update-notifier to tell me new updates are available and the power
manager to tell me my battery is running low.

Is there a way for me to navigate to these objects from the keyboard?
I've tried, but I cannot seem to get to them.
