List editor how to ?

I just started with cubase artist 8.
I opened a Yamaha xf midi formatted file. This reacte a chord track with chord data labels.
I don’ so see any Chordata at all. The manual told about the list editor, but how to acces the list editor isn’t in the manual according a text search.

Please, can any body tell me how to open the list editor with midi tracks.
second question, is there any information available about Yamaha xf midi data vs cubase?
