if you picked 1: you've used a cash register style commodore PET and somehow got used to it, this is normal to you

if you picked 2: you likely have three hands so you don't have to keep twisting one

if you picked 3: trial and error and memorization is easy to you

if you picked 4: once the other keyboards are destroyed, humanity will be your next target.
