Remove Unused Keyframes? I would like to be able to clean unused keyframes from my dope sheet, ones that aren't doing anything.

I read online that you press 'O' in the dope sheet to do this, but I tried it and it didn't work. So, I looked for the hotkey and preferences, and it isn't there!

Is there a way to do this?
I do believe pressing O used to run this tool in the Dope Sheet, but for consistency with the other editors O now seems to enable proportional editing. Now the 'Clean Keyframes' option resides in the Key> Clean Keyframes menu.



WARNING This will reset ALL interpolation back to the F-Curve default Interpolation.
