Backdrop
Use Backdrop to change your module window backdrop (background) within the application. This is similar to changing your "wallpaper" in Microsoft® Windows.
Tip: This is an application-level feature, which means if you change it within one module you will see the effect within every other module for the application.
1. To open Backdrop, click the following sequence:
File from the Menu Bar, Settings; Appearance; and Backdrop.
Keyboard Shortcut: [ALT] [f] [e] [a] [b]
