Soft Key Compatibility
4/19/2010
In order to create a consistent user experience among all Windows Mobile applications, you must follow these recommendations when you implement the soft key functionality for the application. The recommendations also help ensure that the application is compatible with future changes to hardware and the operating system.
Soft Key Guidelines
The left soft key must be a single command, not a menu. It should be the default or most frequent choice. For example, if a dialog box appears, the left soft key might be the command Done, which would close the dialog box and return the user to the application.
If the right soft key is a menu, the top command in the menu should be the most frequently used command. By default, when the right soft key menu appears, the top command is highlighted.
On the right soft key, avoid using submenus that are more than two levels deep.
