Open panel, viewer, and context menus

Panel menus provide commands relative to the active panel or frame. Viewer menus provide lists of compositions, layers, or footage items that can be shown in the viewer, as well as commands for closing items and locking the viewer. Context menus provide commands relative to the item that is context-clicked. Many items in the After Effects user interface have associated context menus. Using context menus can make your work faster and easier.
