Connecting a keyboard to a HP Prime G2? And other questions.

[StephenG1CMZ]

Actually you can get some quite small keyboards and I use the Prime Emulator on Android.
I have recently acquired an Otg phone, so I could attach a qwerty keyboard and use that for sending messages and editing word documents, only switching to AZ touchscreen keyboard when using the Prime.
Whether those smaller keyboards use less power than the full-size ones I don't know.
