Watching a tutorial I can see the teacher open the animation palette found in Window - Animation
I do not have this version, tutorial was dated 2008, I am using CS6 but cannot locate the animation palette, can someone help, is this an additional plugin or can it be located in another location within Photoshop
It's now called Timeline.
This was a concession to most NLE (Non Linear Editor) programs on the market, like Adobe Premiere Pro, where the Timeline is the basis for editing Video.
Thanks for steering the OP in the right direction.
