1)
Factory Reset does not wipe the program from the chip, but it does erase any BlueTooth pairing information.
2)
Intentionally requires a hand shift or two hands. On 'flat' keyboards I shift my hand and do this with Thumb on Far, Index Finger on Center, Middle Finger on Far, and Ring Finger on Index Key. On Curved Chorders I use two hands or body for 3 thumb keys.
3)
currently experimenting with this chip - see nRF52 Chorder
4)
Shows HID mode and power state. It first flashes Blue LED twice for HID_BLE, Green LED twice for HID_USB, or Blue Green Blue Green for HID_AUTO, it then pauses for 1/2 second and then flashes Green twice for power from USB or twice Red if using internal battery only.
5)
System starts in HID_AUTO, pressing this key changes to BLE only or USB only depending on current connection. After that it toggles between BLE only and USB only.
