Media pager: a spin of the wheel flies past the posts and lands snapped on one. A notch was a step, and a breath between steps meant a flick of the wheel moved two or three pictures at most (Adam). Now each notch adds a post to go — the third and later notches of a quick run (within 400 ms) add two, so a flick is a few posts and a spin a dozen — and the pager glides through them with the pictures passing (pagerFly: a longer glide, 100 ms + 110 per screen, eased out), landing snapped on the last. The posts passed are not arrived at: the slide observer stands down while flying (no clip starts, nothing marked seen, no counts asked), and the landing arrives (pager.arrive, the observer's old body). A notch back against a flight catches it on the post it is passing and steps back from there; a touch or a key catches it too (pagerGlide now takes a duration and an onDone that pagerHold fires on interruption, with the snap restored). A notch from rest is the single quick step it was; sideways notches and trackpad runs step as before. tools/pager-wheel-test.js: a spin of five flies eight posts on and lands snapped (gliding mid-way), the spin back, a notch against the flight. feed-video-pager-test's two failures are on HEAD before this.

Media pager with a mouse: the wheel pages, ctrl+wheel zooms, arrows for the pointer. Adam reached for the scroll wheel in the pager on his laptop and nothing useful happened: a notch scrolled the snap container a hundred pixels and the glide's snap put it straight back (a headless probe of the live pager: scrollTop stays 0), so the arrow keys were the only desktop way through. Now a wheel notch is a step — down the next post, up the one before, a sideways notch (a trackpad's, or shift+wheel) along the post's pictures — with a 220 ms breath between steps so a spin of the wheel is a step or two, not five; a trackpad's run of small deltas is one step per run (its first 40 px, the rest until a pause is spent). Ctrl+wheel zooms the picture at the cursor, which is also what a trackpad's pinch arrives as in Chrome (attachZoom's new wheel: 'ctrl' mode, 0.004 per unit); while zoomed the plain wheel pans it, and at 1× it is the pager's again. And where there is a pointer to hover with (hover: hover and pointer: fine), arrows: up and down at the right edge, left and right when the post has a picture that way (has-left/has-right, set as the slide on screen changes), faint until the pointer is over the pager. The keys, the wheel and the arrows share one step (pagerStep). No mouse drag-flick: discrete steps suit a pager. tools/pager-wheel-test.js (CDP mouseWheel is always a 120-unit notch to Chrome, so a trackpad run is dispatched page-side; headless has no hovering pointer, so one is given with --blink-settings); feed-picture-pager and image-zoom tests pass.
