Animation button not showing up when I select animation controller or animation

I want to edit an animation in my project. When I double click it, the interface where I can edit frames and such never appears.

I'm watching a tutorial on how to make platformer game and here how it is in video:

Here it is on my machine:

Notice how there is animation button near the Animator on top. I don't have it on my Unity. No amount of clicking, selecting and fiddling lets me open animation to edit. I only get some preferences on the right pane and thats it.

How do I fix this?

I'm using latest Unity 4.6.1f1
