I have an active knight and want to move it to a different intersection along the same road? How do I do this?

Klick on the knight, klick on an open spot along the same road.

This is easy to miss, because if you klick on the knight, in the top row you see the options for this knight ("upgrade", "move robber",...) but the option "move knight" is never mentioned there. But it still works as I wrote above.
