Any single open window in Corticon Studio can be the active window. Indication of active status is provided by the window's tab color. As shown below, the active window's tab is colored white, while inactive tabs are colored gray. “Shifting focus” (that is, activating a different window), is accomplished simply by clicking anywhere within an inactive window or on the window's tab.

Below, the tabs of four Corticon Studio windows are shown in the editor space.

  • The active window's tab is white, Order.ecore
  • The .ers file is not the active window. It has been changed but not saved, as indicated by the asterisk preceding the tab's name.
  • The .erf file is not the active window and has been saved, but the red square overlaying the window's file type icon indicates there is an error somewhere in the file content, as described in the Problems window.
  • The .ert file is not the active window and has been saved, but the yellow triangle overlaying the window's file type icon indicates there is an warning somewhere in the file content, as described in the Problems window.
