It's strange to me that it's not possible to remap the mouse joystick to arrow keys, as per multiple posts, both newer and older.
My mother has only one usable hand. She loves video games, but hasn't been able to play most of them her whole life due to the controllers. She's also a writer who has also been looking for a good portable one-handed Bluetooth keyboard for ages. This would be the perfect device for her needs if it was possible for the joystick to be used like an actual joystick like one would expect.
Going without the "mouse" functionality on the Twiddler (which many users on this forum seem to agree is poor) would not be a loss. In fact, one of the things I really like about this device is that a traditional track pad, mouse, touch screen, et cetera is still perfectly usable while wearing the Twiddler on the same hand.
(Additionally, I'm excited about the potential for using the Twiddler one-handed in AR or VR, but having an otherwise phenomenal text entry remote that lacks straightforward arrow keys kind of feels like having a Ferrari without wheels.)
Can this please be made possible in future generations of this product?
