The following are two really basic shortcuts for working with NetBeans editor windows that will be added to the Keyboard Shortcuts card for NetBeans IDE 7.2:

1. Ctrl-Alt-PgUp/PgDown: Shortcuts for switching between editor types (e.g. Source, Design, History buttons). Switching between the editor types is a frequent operation sometimes, e.g., when using GUI builder, and while it can be done easily via mouse, or from View | Editors menu, it is very handy to know the shortcuts as well.
   
   
2. Ctrl-PgUp/PgDown: Similarly, these are shortcuts for switching to next/previous opened document (tab). Note this is not like Ctrl-Tab that cycles in the last used order, but going through the tabs as they appear in the editor.

Both shortcuts should fit into the "Opening and Toggling between Views" section. These are important to mention on the card because they are not visible anywhere else in the UI (as there are no menu items like "Go to next/previous editor type" or "Go to next/previous document").
