shape keys - no keyframes?

Support Animation and Rigging

I’m trying to lip-synch in Blender 2.58 with shape keys.

So I made shape keys for mouth shapes like “A” and “S”.
I go over to the dopesheet window and switch it to the Shape Key Editor.
Then I ADD NEW and name it “speaking”.

The key shapes appear to the left, but there are no sliders?! and I can’t add keyframes?
Am I doing something wrong?

There is a button to show/hide sliders

Look in the View menu to show sliders.
It can be problematic adding the first keyframe. Either add a keyframe in the shapekeys panel or I’ve found if you move the slider in the Shapekey Editor it creates the first keyframe and then accepts further keyframes with the I key
