The knock
In full screen, the edges belong to your app — panels, timelines, tools live there. So hovering never summons a dock. When you want one: touch the edge, pull back, touch it again. That's the knock.
First the problem: reaching for tools or menus keeps summoning docks over your work. Then the fix — Reveal set to Knock — and the same edges go quiet until you knock: left bezel, top bezel, any edge you gave the gesture to.
Touch the edge and pull back: a thin glowing line appears — Docksmith heard you, and the window for the second tap is open exactly as long as the line shows.
No timer to memorize, no failed gestures to wonder about. The feedback is the timing.
Some "full screens" aren't: Photoshop's fullscreen-with-menu-bar mode is, to macOS, an ordinary maximized window — no app can tell them apart. So the knock is also a per-dock choice: set a dock's Reveal to Knock and its edge answers only to the gesture, fullscreen or not. (True borderless full screens — games, kiosk players — get the knock automatically.)
Your bottom dock can stay on hover while the top one demands manners. Each dock, its own door.
Brisk, Standard or Relaxed: one dial scales both halves of the gesture — how brief a tap must be, and how long the edge waits for the second one. The glint always shows the live window, so every tempo teaches itself.
An edge shared with another display has nothing to land on — the pointer just keeps going. So there the gesture becomes what its name says: two knocks. Cross onto that screen and back, then do it again while the line shows. Going over to work never summons anything; nobody bounces twice by accident.
