A new window is opened containing the
document you are editing.
The remaining commands on the Window menu let you organize your
windows horizontally or vertically with respect to each other, so
that they do not overlap, (Window > Tile Horizontally
and Window > Tile Vertically) or in a cascading
arrangement in which they overlap each other (Window > Cascade).
Note that you can switch from one document window to another by
selecting the window name at the bottom of the Window menu.
About Minimizing and Maximizing Windows
In the top right corner of the window, click:
Minimize
to minimize the size of the window. In some cases, this
means to hide the window.
Maximize
to restore the window to it largest size. The restore process is
based on the window's height (not on its width) and objects
displayed in the window are zoomed accordingly.
Restore Down
to make the window back to its previous size and location. This icon
is only displayed when the window is at its largest size.
About Filenames
The size of filenames displayed at the bottom of the Window
menu must not exceed 32 characters (without the extension) and the
extension part after the dot (.) should not exceed 13 characters.
Otherwise, filenames are truncated with ".." in between.
