PREREQUISITES A touchscreen device, like my Surface Book, and what I believe are the default touch-friendly settings, namely: within General → Tools, touch painting is disabled, touch rotation is enabled; and in Canvas Input Settings, Pan Canvas has an entry for type Gesture, action Pan Mode. STEPS TO REPRODUCE 1. Place one finger on touchscreen within the canvas region, and move it before releasing the finger from the screen. OBSERVED RESULT Nothing happens. (Meanwhile, two fingers on the touchscreen activates full zoom/rotate/pan, which is not a suitable substitute because it messes up zoom and rotate, which I don’t want.) EXPECTED RESULT The document should pan with my finger.

No, single-finger panning just isn't implemented, so this is a feature request, not a bug.
I’m curious then, what *is* the pan canvas gesture? I just assumed that single finger touch would be what it was, given that that’s the universal standard unless single finger touch is drawing, in which case two finger panning is the thing to do, with zoom/rotate snapping to the original values if both of those are supported also. It’s hard to tell with all these things since it just says “gesture” rather than what type of gesture, and the docs don’t talk about gestures at all.
