Discontinuing window updates


    Press the Caps Lock key to prevent After Effects from updating Footage, Layer, or Composition windows. This is useful for a Layer or Composition window that takes a long time to update. When Caps Lock is active, all open Footage, Layer, or Composition windows display the last update you made before pressing Caps Lock, regardless of the changes you make. As soon as you make a change that would appear in a window, After Effects adds a red outline to any affected windows, and the windows are not updated. After Effects continues to update window controls such as motion paths, anchor points, and mask outlines as you move them. To resume window updates and display all changes made while Caps Lock was active, press Caps Lock again to deactivate it.
