back/forth navigation buttons on sequential web content

should be locked in the same absolute location within the window, so that different-sized content doesn't make the user have to refocus on the navigation to proceed with the sequence. and while i'm here, to the power-washers stripping the paint off the building next door who are starting up the compressor now, at 5.45am EST: who do you think will be first against the wall when i am king, etc?
