Q2: When does the keyboard needs to be recharged and how do I know it is full?

When the M indicator light starts flashing in red, it is in low battery indication and you need to plug in the USB-C cable to charge in time.

During charging, M indicator will stay in solid red color (any mode) and restore to current connection mode color status when it’s fully charged.
