What if there is not a key command for an action?

Double-check the application's help section for any keyboard commands you may have missed. Even though they might not be listed in a menu, as long as the application supports them, they should work with the PowerMate. Some applications (Logic Pro, for example) will allow you to create your own shortcuts within the application itself. Keep in mind that each application does have its limitations, so it may not support the function that you desire.
