Expand the Position Y parameter
In the Timeline, expand the Position group's Y parameter. This is as far down as we can go. We are now looking at the actual value for this parameter at this frame. More on that later. Note the green box to the left of the value. This box represents the function curve's color. Clicking on it will open the Apple color picker, allowing you to change the function curve's color.

Navigating the Timeline
Navigating the timeline is the same as in any other view. Shift - click and drag will pan. Option - click and drag will zoom. Pan the view a little to the right as shown.

Click in the bottom right corner of the palette. Hold the mouse button down and drag to resize the window while holding the Shift button down as shown.
