Keyboard input

Hi,

I spilt some tea on my win10 laptop keyboard and now the down arrow doesn’t work, as you can imagine it’s a PITA trying to navigate within kodi.
I’ve tried a couple of key swappers but they don’t work within kodi.

Outside of kodi i can use the direction arrows on the number keypad to move around.

Is there any setting within kodi i can change so it receives the input from the pad rather than the normal direction arrows?

Thanks
