You can create multiple windows for the same document using the New Window command. New windows have the same size, magnification, and layout as the original window and open at the same page and on top of the original window. When you open a new window, Acrobat adds the suffix 1 to the original filename and assigns the suffix 2 to the new window. You can open multiple windows with the suffix incrementing with each new window. Closing a window causes the remaining open windows to be renumbered sequentially; that is, if you have five windows open and you close the third window that you opened, the windows are renumbered with the suffixes 1 to 4.
