MOUSE SPEED SLIDER

Hi Guys,

I'd love to add a custom slider to the Touch Bar that controls the speed of my mouse/trackpad but my AppleScript skills are none existant.

Can anyone help?

Thanks in advance

Trying to achieve something like this. I fail UI scripting, I don't manage to get the slider to be toggled :frowning:
And shell is effective free for some reason.
I'm gonna keep on looking a bit, but no garanties taken.

Thank you.
