how to add an IPO curve for dRot channels?

I need to do an IPO curve for the dRot channels, and I don’t know how to insert keys.

You open the IPO window with the Object selected and in Object Mode. Find dRotX in the right-hand column and Leftclick on it (it’ll turn white) then Ctrl-Leftclick on the IPO window grid where you want the first keyframe to appear, then second, third etc.

Then do the same for dLocY and dLocZ if necessary.

After you’ve inserted the points, you can edit them manually by tabbing into Edit Mode with the curves selected and using the Transfrom Window (N key) to set exact positions.
