Playback marker in key editor?

Hi guys,
after tons of lurking, I myself need some help with a specific problem, I hope you guys can help me out:

I was working with Cubase 5 and 6 before, and I often used the key editor to be able to play the notes with my violin while recording.

But after upgrading to Cubase 8, I noticed the playback marker/cursor in the key editor was somehow missing.
How can I get it back?

Surely the function is there, and I’m too blind to find it. Autoscroll seems to work fine. Help!
