tutorial question

while following the tutorial found here: http://mediawiki.blender.org/index.p..ven Shape Keys

I came across a line that says: "Name the left bone Close, the right bone Smile. I understand this but don’t understand the next sentence: "name the armature object “Driver.” Where do I go to name the Armature Object?

F9, Links and Material tab, OB: field.
