File requires root permission to be written, but sometimes we forget to add sudo before vim command.
The result is after editing the file with a lot of changes, :w cannot save them.
This can be avoided by adding a simple command to $HOME/.vimrc:
cmap w!! w !sudo tee > /dev/null %
Then when we type :w!!, it will be mapped to :w !sudo tee > /dev/null %, which will let we save the file
with sudo without re-opening the file.
Normally, a Bevy application can be exit with AppExit, but on Android, that is not enough and can cause the app fails to reopen. To completely exit the Bevy application on Android, we need to do that from the Android side.

Got the keyboard and pretty happy with it, except one thing: capslock/numlock led doesn’t light up in wireless mode, although their functions work fine. In USB mode, the leds light up normally.
