I got through filling all the front areas, and then extruded and beveled all my buttons. I went to extrude my screen shape and realized the top of the screen shape is connected to the piece next to it so I'm not able to extrude the screen down. Is there anyway to go about disconnecting these edges? Screenshots below
The correct answer would be to press E when you want to Extrude it, not just try to move it down...
