Remarks

UIKeyCommand objects are only generated with an attached hardware keyboard.

To create keyboard accelerators, developers must create a Selector that is associated with a method of type Action<UIKeyCommand> with an appropriate ExportAttribute:

[Export("NewFileAccelerator:")]
void NewFileAccelerator(UIKeyCommand cmd)
{
   //etc...
}

public override void ViewDidLoad ()
{
    base.ViewDidLoad ();

    var actionSelector = new Selector("NewFileAccelerator:");
    accelerator = UIKeyCommand.Create((NSString) "N", UIKeyModifierFlags.Command, actionSelector);

    AddKeyCommand(accelerator);
}
