Knocking on is an action applying to one thing. Understand "knock on [something]" as knocking on.

Instead of knocking on something which is not a door:

say "There doesn't seem to be much point to that, as [the noun] [aren't] a door."

Check knocking on an open openable door:

say "[The noun] [are] already open. Why bother knocking?" instead.

Check knocking on an open door when the noun is not openable:

say "That would prove difficult." instead.

Report knocking on:

say "You rap loudly on [the noun]."

Report someone knocking on:

say "[The actor] [knock] on [the noun]."

Carry out someone knocking on a door when the noun is visible and the actor is not in the location:

say "Someone is knocking on [the noun]."

Liminality relates a door (called X) to a room (called Y) when the front side of X is Y or the back side of X is Y. The verb to be a threshold of implies the liminality relation. The verb to be liminal to implies the liminality relation.
