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.
