HoloLens 2 system keyboard key detection

How to detect a HoloLens2 system keyboard key such as Enter key through C# scripting in Unity-MRTK ?

Hi @rueilmanzambi, please take a look at Unity documentation here, and for an example you can use

public static bool GetKeyDown(KeyCode key);

@MaxWang-MS , how would we implement it in such a way that it knows that we are working with the HoloLens system keyboard? I can't see a member of TouchScreenKeyboard that would work for key detection. I don't know if there's a class that can be inherited to accomplish that task.

Do you need to differentiate between HoloLens system keyboard and other types of keyboard? If not, the API I mentioned should work just fine - that API does not care whether it is HoloLens keyboard or normal physical keyboard, it should just work.

Finally figured it out, thank you for the help

@MaxWang-MS Wondering as a follow up to this question if there's a good way to detect the X key being pressed on the system keyboard other than binding to the event that gets called once the keyboard gets hidden?
