Access to Player control for music

Hello all,

I installed Aeon Tajo yesterday, and I am still amazed at how it looks. Many thanks!
One thing that I couldn't figure out was how to control the music. I can easily start a song, or album
But then getting to the player control is difficult. I must be missing something.
I am using a Google chromecast with Google TV. So I have very little buttons on my remote :-)
Is there an easy way to access it and stop the song again, or pause it, with my remote?

Regards,

Bert
