How do I change/edit the name of a label in Blogger (blogspot)

hack around it ;)

1. go to edit posts
2. click the label on the left you want to change to select all posts under that label
3. make sure all are in the view (show 100/page or whatever) and click select all
4. apply new label to it
5. select all
6. remove old label

Thats all :)
