Sliders to change text size - can't find any of them

[pleasemakeitwork 10]

I just download Skitch for Mac osx. I am using this official EN tutorial http://evernote.com/skitch/guide/mac/#4    I want to change the size of inserted text.  No matter what menu item that I click nothing that looks lie a color picker pops up and nothing like the size slider pops up. I must be missing something.  How can I change the size of text? thanks

When you click on text you should see four nodes appear at each corner, these should allow you to scale the text.
