Add a deskmat or 3m sticky foot, it helps a lot.

Can you share a link? Are you referring to rubber feets that stick on or feet made of sticky material?

My keyboard came with some small rubber feet. Like these, although smaller: https://www.rapidonline.com/3m-bumpon-black-transparent-self...

I have it on a "gaming" mouse mat, i.e. an enormous mouse mat.

Right, or blu tac, or anything else sticky (well maybe not anything else sticky).
