Not possible to use key when cursor is hidden?

I have a puzzle where i want the player to use a key-stroke in stead of the mouse.

I hide the cursor and have written appropiate action for the key-stroke.

But it seems that key-strokes are disabled when cursor is hidden.

Is that so?

Yes, but you can use the Lua key event handler - probably, or you could just set the mouse cursor as a transparent one & disable interaction by overlaying an interface that's the same size as the default game resolution.
