Using the numeric keypad keys as class shortcuts

Dear community (and labelbox team),

I started labeling in a new project and switched to an iPad for easier drawing of segmentation masks with the Apple Pencil.
It does work considerably better than using the mouse so I want to commit on that workflow. I now try to accompany the iPad with an external numpad keyboard (no letters, just the numbers). My goal is to draw the masks with the pencil and quickly select classes with the numpad on the other hand. Unfortunately it seems as if the numpad keys are not recognised by the labelbox editor (only the standard numbers).
That does make sense as the numpad numbers have a different underlying hex code.

Do I oversee a setting that would allow me to use the numpad keys or should I file a feature request for that?

I think the numpad is in general a superior layout for class selection, as all keys are easily and confidently reachable with one hand (in opposite to the far distributed numbers on the general keyboard).

Thanks for your feedback and best regards,
Johannes
