Live Paint

Live Paint - student project

Live Paint - image 1 - student project

I made the drawing using the pencil tool and then used live paint to add color.  When I previously used live paint I would use the black arrow key to select everything and then just press K on my keyboard which brings up the live paint bucket.  In the video you selected everything and then went to object --> live paint --> make.  Can you tell me what the difference is between the two methods and let me know if I am doing it wrong by just select the keyboard shortcut to start painting.

Thank you!!
