Transforming within a level sequence

I currently have a level sequence with animated transform values, too many keyframes to edit individually… I want to copy the rotation values over to new keyframes but inverted (Transform Mirror Y). Any idea how to do this since it seems simple but i cannot find a way. Thanks

If you want to invert them in time, you could copy/paste the keys, multiply the times by -1 and then slide them back into place. You can use the Transform Selection menu item under the wrench icon and then type in -1 and hit the * button in the pop up.

Ah sorry i should have made it clearer, i want to invert the rotation values. Similar to how to you mirror the Y, X or Z of an object, but I need to do that for the whole level sequence keyframes.

Probably best to do that in the Curve Editor - select all the keys you want, use the Transform tool interactively to flip them.

Or perhaps the Multi Scale Tool and type in -1 to YScale

Thanks for the help mate that worked well
