How to add keyboard shortcut of OEM keys in Keyboard Accelerators in WinUI 3, XAML

Question

Hi. I am creating an app in WinUI 3, C# Xaml. In the app I have a button which has the "+" symbol. The Keyboard shortcut for the button is only showing the numeric pad "+" key. How do I add a shortcut of the shift key and the OEM plus key? I've explored a bit online and found out that there is no Virtual Key for the OEM keys. Is there any workaround for this? Or can I set a keyboard shortcut using the enum value of the keys. Kindly help.

Accepted Answer

According to Localize the accelerators,

Keyboard accelerators are implemented as virtual-keys. Localized accelerators must be chosen from the predefined collection of Virtual-Key codes (otherwise, a XAML parser error will occur).

and

VK_OEM_PLUS	0xBB	For any country/region, the + key

You can set VK_OEM_PLUS programmatically.

        myButton.KeyboardAccelerators.Add(new Microsoft.UI.Xaml.Input.KeyboardAccelerator()
        {
            Key = (Windows.System.VirtualKey)0xBB,
            Modifiers = Windows.System.VirtualKeyModifiers.Control
        });
