Cannot delete keyframe in Blender 2.79

Support Basics & Interface
1

I upgraded from Blender 2.77 to Blender 2.79. For some reason every object has a keyframe on zero that I cannot delete. A screenshot of my dope sheet is included. I have checked every line and everything looks okay. I assume the bright orange on the summary line is indicating a problem.

The orange line means the value is the same between two keyframes. Have you tried both X and DEL to delete keyframes ?

I’m not sure how to delete a keyframe with X. If I select the object it deletes the object.

That would be X while hovering the dopesheet, not the 3DView. Hotkeys are editor-dependent like that.

Thanks Hadriscus. Found the problem. It was in the grease pencil. I deleted there.
