@Terry Aney:Indeed, you are missing something. The Alt+Right Arrow is bound to Edit.CompleteWord at the Text Editor scope. Shortcut keys apply at various scopes and when you are in a text editor, the Text Editor scoped shortcuts take precedence over the Global shortcuts. In the keyboard settings options page, if you press Alt+Right Arrow while the focus is in the "Press shortcut keys", you'll see the "Shortcut currently used by" will be populated. If you open the drop-down box you should see that Alt+Right Arrow is bound at four other scopes (including Team Explorer, Workflow Designer and XML Schema Designer). If you want the Global shortcut for Alt+Right Arrow to work while you are in any of these scopes (in particular, Text Editor scope), you need to override or remove these bindings.
