IPO keys

How do I add IPO keys for things like time / speed etc…

like, I can add things for materials by pressing “I” in the materials window, and I can for vertex keys by pressing “I” in the edit window, and “I” in the object window for ROT,LOC etc…

what about all the other IPO keys?

select the ipo curve of your choice and press I in the IPO window.

In the IPO window (Shift+F6) you can select the curve and press Ctrl+LMB to add a point, you can enter edit mode with TAB for more control.
