BH Weather on key

[limit_touch]

Black Hole 3.0.1C Vu+ Solo OE 3 contains extension BhWeather.
I want to reassign the yellow button (long key) to display weather. It is possible?

I have tried to use the MultiQuickButton plugin, but the file "BhWeather\plugin.py" does not exist and this does not work.

Black Hole 3.0.1C also contains extension BhFullBackup. But how I can use it I don't understand too.
