If I press something on the Display keyboard, say "D (Colour Coding)" -> "Z (Under Colour)", I get a popup.
Due to my "sloppy mouse" in X, sometimes I end up putting keypresses into the Display or keyboard window instead of the input popup, then when I finally fill in/okay the popup, those key presses are processed by Display, making a great variety of unintended things happen since I was intending to type into a box.
