Add Keyboard support #169
Description
Is your feature request related to a problem? Please describe.
This is the best Sudoku app I have found across all platforms I have used. but I'd like to use it while in Samsung Dex and within Waydroid on my computer, but constantly using a mouse or trackpad is annoying
Describe the solution you'd like
I would like to see support to use the number row, 10 key (number pad) and arrow keys to use the app
Shift could also be used to initiate a note
Describe alternatives you've considered
key mappers, but they can always be hit or miss especially with multiple screens like Samsung Dex
