Solved Key frames in Vegas Pro 13

I had occasion this week where I needed to use Key Frames to gradually apply an effect (eg Brightness & Contrast) Now in Vegas Pro 8 Key frames usually came up. This does not appear to happen in Vegas Pro 13 - well they are very sporadic. Do I need to set some parameters in Options perhaps to make them appear?

You need to press the little clocks for each control you want to keyframe.
When more keyframe lines appear, you may need to drag your window out to a bigger size and also drag top of timeline up to reveal.

Yes, very helpful thanks Derek. Found a couple of things: I had set the keyframe box to small, so could not see the "tracks". Another important feature - the setting of columns - I had this set at 3 colums which made the keyframe box very wide, almost hiding the preview window. Setting this to 1 column made quite a difference.
Good job you provided your sample screen shot as a reference, where I could see what I needed to adjust.
