Change Name

I can change the track name.
but how do I change the name of the project track.
In Cubase 7.5 it was on top of the inspector but now I don’t see it there.

I am not sure what you mean by “project track” but I think you may be looking for the “info line” which can be turned on and off with the layout button on the top left.
