I noticed you have to hit TAB after selecting a curve, in order to modify any of the keys on that curve. Is there a way to just click on a curve key Directly without hitting TAB everytime you change curves?
the IPO window is a bit like the 3D view with an Object mode and an Edit mode. If you select the IPO curve and do not Tab, you can G (grab) and S (scale) and R (rotate) the whole curve. However, if you want to move individual control points, you need to Tab into Edit mode.
