On Stack Overflow, there is an "edit tags" button or somesuch that will appear when you mouse-over the area to the right of the tag list on a question. It allows you to edit the tags of a question without bring up the whole edit box for the rest of it.
Even when you can freely edit questions and answers, I find this button useful for just editing tags. Do other people not see it, or is it just me? Is this intentional or a bug in the site?
