IMPORTANT: If you use the POWER-click (i.e. hold down the SHIFT-key while clicking with the primary mouse button (see Using the mouse) or RETURN (see Using the keyboard)) on a source row in the ECB-Sources or ECB-History windows then the source will not be displayed in the edit-window but it will be scanned in the background and all its contents (e.g. methods and variables) are listed in the ECB Methods window (see ECB Methods-buffer. So you can get an overlook over the source without changing the buffer in the edit-window.
