Binding any of several keys to "hide map" and pressing them doesn't hide the map.
Buttons that don't work:
Arrow keys (up down left right)
<>| ("OEM 102", Nordic keyboard, below A and to the left of Z)
All other buttons on my Nordic keyboard (Microsoft Bluetooth Keyboard 6000 Nordic) work to hide the map with naturally except for the buttons you can't bind such as Esc, 0-9, F1-12… and even volume up and volume down buttons work!
I suggest that the devs make sure every button can be bound to every command properly as other commands may be the same issue and this issue may also exist for other buttons that I haven’t got on my keyboard.
