Bind Cmd + + / Cmd + - / Cmd + 0 to Buttons (for zoom) or other keyboard shortcuts

First of all: thanks a lot for this amazing tool - it's a real masterpiece!

It would be great (and I think very easy to implement) if you could make it possible to bind mouse buttons to keyboard short cuts. By this means you could e.g. easily implement native MacOS in-App-zoom by binding Cmd + + / Cmd + - / Cmd + 0 to button 3, 4 and 5 of an MX Master 3S.
