When creating a new document or loading an existing document, a document window opens containing the first page. Each document displays in its own window, and more than one window for each document can be opened at any time.
One window will always be the active window, and thus its document will be the active document.To activate a window, click on the window's content. Another way to bring a window to front and to activate it is to choose its name from the Show Window submenu.
To open an additional window for an existing document: Choose New Window from the Window menu. This will open another view of the current document, it does not create another document.
To close an extra window: Select on the appropriate document window and choose Close from the File menu or click on the Close button in the upper left corner of the document window.
To bring to front an obscured window or reveal a hidden window: Choose the name of the window you wish to open or bring to front from the Show Window submenu in the Window menu. This submenu lists all open and hidden windows. Select All if you want to open all hidden windows.
To hide a window: Choose the Hide submenu from the Window menu. Select Current to hide the active window, Others to hide all but the active window or All to hide every window. Alternatively, you can also choose the name of the window to hide from the list of open windows.
To rename a window or preview color seperations on screen: Shift-click on the name of the document window in the Hide or Show submenu from the Window menu. A window requestor will open, this requestor allows you to rename the document window view and to show the color plates one at a time to check if the right spot colors or overprint/knockout options are set.
