How do I position my timeline to show the values in range of start frame and end frame?

I am following this video for Curve Editor

And my timeline should show me from 1 - 1200 is what I expect (want).

What it shows me is negative -1600 to 300.

I tried arrowing to the right, not sure what else to do. Is there an ‘Auto Fit’?

I don’t really see the value in negative numbers, unless you need stuff “transforming” before it comes into view maybe ?

Thanks, my camera does move, so that is the cool part.

Now I am really confused. I don’t know what I did, but now it looks correct:

I must have clicked something, because this is the view I was expecting earlier.
