I am using a Thinkpad and try to get into the habit of using an external keyboard, which also has a Trackpoint.
With the internal keyboard, I can use the middle mouse button to click (e.g. paste, or open link in new tab), but if I hold the middle button and move the Trackpoing, I am scrolling.
For the external keyboard, I am observing that scrolling works, but it also often (not always) issues a click event, and suddenly my editor is full of pasted stuff
The xinput properties seem to be set the same:

Where else should I look? Is this “Customer Control” device relevant?
