Key Editor Muting All Audio

I’m sure this is a setting somewhere, but I can’t find it. And I checked the manual and can’t find the answer online.
Cubase Pro 12

When ever I click anywhere in the key editor all audio playback is muted. I’m guessing ths is a key shortcut that I accidentally typed because it just started doing this today.

Help is greatly appreciated. Thanks.

Hi, double-check if the S(solo button) is engaged in the editor(key editor in your case) or try to type s key on your keyboard while you are in editor.

Thanks so much. The solo button isn’t showing but the S key solved it. Thanks so much.
