What is this?
This is an utility for programming small keyboards like this one:
There are several modifications of such keyboards with different number of buttons and knobs. Utility was tested to work with:
- 3×3 with 2 knobs
- 3×4 with 2 knobs (Bluetooth version)
Such keyboards are popular on AliExpress and seller usually sends software for programming, but it:
- requires Windows,
- is very ugly and inconvenient,
- can only program one key at a time
- don't expose all keyboard features

Monitoring generated keyboard and mouse events
Most simple (and cross-platform) way I've found is using keyboard and mouse Python modules.
Monitoring keyboard:
pip3 install keyboard
sudo python3 -m keyboard
Monitoring mouse:
# Latest published 'mouse' module doesn't support MacOS, so use latest version from Git:
git clone https://github.com/boppreh/mouse
cd mouse
python3 -m mouse
