M8: Scale tool drags pivot on the opposite handle, and its origin starts at the centre

Measured in Figma's web app (2026-11-09): a handle drag ignores the origin grid and pivots on the opposite handle's point (Alt: the centre); only the numeric Scale field uses the origin, which starts at the centre. scale_factor drops the anchor, tool.scaleAnchor defaults to c, and K, 2, Enter now scales about the centre.

Cmd/Ctrl-click on a padding field sets all four sides with the value typed, a documented auto layout shortcut; a fill per region of a vector: with regions selected in edit mode, the Fill section and the fill commands edit those regions' own fills, as Edit vector layers says (#1875); the Fill section of a text whose characters were coloured differently while editing shows mixed content, characters that all share fills the layer doesn't have show those, and a layer-level fill edit reaches every character (#1856); a number field scrubs when dragged with Alt held, as the help center's scrub section says, not only by its label; reuse visible layer selection roots (M8); ; with a shape or frame tool chosen and nothing selected, the arrows show a placement crosshair in the middle of the view and move it, and Enter places there, as Accessibility at Figma says (#1839); text direction per paragraph: Text ▸ Text direction forces a paragraph left to right or right to left, as Add right-to-left text says (#1830), with `text.direction`, `node.set textDirection`, the Type settings control once a right-to-left script is in the text, inspect, the CSS `direction` and the `.fig` lines' `sourceDirectionality`; the boolean operation menu in the Design panel leads each entry with an original icon drawn in code, a filled preview of the result (#2003); a press on the open gradient's handles or stops on the canvas keeps the colour picker open through the drag, as its own control (#1852); a click with the Bend tool on a sharp point curves it, its handles along the line between its neighbours, as Edit vector layers says (#1875); wrap style: Auto, Balance and Pretty on a text layer decide where its lines break, as Explore text properties says (#1827), with the Type settings control, `text.wrapStyle`, `node.set wrapStyle`, inspect and the CSS `text-wrap`; Backspace or Delete at the start of a list item keeps the item's indentation level, as the lists article says; max lines on auto-width text keep it auto width, hugging that many lines, as the text properties article says; superscript and subscript are synthesised where the font has no glyphs for them, from the standard glyphs shrunk and shifted by the font's OS/2 metrics, and a run mixing available and unavailable glyphs is synthesised Line truncated
 
 Fine canvas control is what Figma users feel first: handles, snapping, nudging, modifier keys,
 drag behaviour, numeric precision. This checklist covers the tools, gestures and panels. Status:

 | Enter with a shape or frame tool chosen | done | places what a click makes (100×100, lines 100 long, sections 400×300) in the middle of the view, selected (`tool.place`); from the toolbar, Enter on the chosen tool. With nothing selected, the arrows first show a crosshair in the middle of the view and then move it by the nudge amounts (`tool.crosshair`; Shift the large one), and Enter places there; Escape or a tool change takes it away ("Use the arrow keys to activate the crosshair cursor. It will appear in the middle of the viewport indicating where the new object will be placed", Accessibility at Figma; #1839) |
 | Alt-drag duplicate | done | the copy snaps to the layer it came from too (edges, centres, equal spacing); Duplicate (Cmd+D) then repeats the copy's offset, also after a Duplicate whose copy was moved, as long as the copies stay selected (the documentation doesn't say; pinned from community answers) |
 | Drag threshold; double-click into groups and text | done | a press moves or resizes only once the pointer has travelled 3 px on screen, so a click or double-click made with an unsteady hand drags nothing; a double-click goes one level into a group and the next one edits the text under it, wherever on the text it lands, with all of it selected (a double-click in the text being edited selects the word) (`double_click_tests`); Enter on a selected text does the same (all of it selected, typing replaces it) and Escape leaves editing with the layer still selected (`text_enter_tests`) |
-| Scale tool (K): handles about an anchor, live factor, panel | done | Pressing K opens the Scale section with its factor field focused and its text selected; typing 2 (or 2x, 1.5) then Enter scales the selection by it about the panel's origin (FigCraft's starts at the top left; Figma's grid starts at the centre, left for a follow-up because the origin also sets where a handle drag pivots, which is not measured), as one undo step, then closes the section and returns to Move with the selection kept; Escape in the field closes it, back to Move, nothing changed.

+| Scale tool (K): handles about the opposite handle, live factor, panel | done | Dragging a handle ignores the origin grid and pivots on the opposite handle's point (the opposite corner, or the opposite edge's middle for an edge, which scales both ways), with Alt on the centre; the origin grid (`tool.scaleAnchor`) starts at the centre and sets only what the Scale field and the W and H fields keep fixed (W and H with a non-centre origin are unmeasured). Measured in Figma's web app, 2026-11-09. Tests: `a_scale_handle_drag_pivots_on_the_opposite_handle_whatever_the_origin`, `the_scale_origin_starts_at_the_centre`. Pressing K opens the Scale section with its factor field focused and its text selected; typing 2 (or 2x, 1.5) then Enter scales the selection by it about the panel's origin, which starts at the centre, as one undo step, then closes the section and returns to Move with the selection kept; Escape in the field closes it, back to Move, nothing changed.

 | Nudge 1 / Shift 10 (preference), Cmd+arrows resize | done | arrows reorder auto layout children |
 | Smart guides: edges, centres, equal spacing (between two layers or continuing a row's gap, labelled), spacing labels, parent, layout grid, ruler guides | done | red, `snap.rs`; a guide dragged out of a ruler or moved snaps to layer edges and centres too (Snap to Objects; Cmd/Ctrl suspends), on its own axis only; page guides see the page's top-level layers, frame guides the frame's box, layout grids and every layer in it, along a rotated frame's own axes; thresholds not yet compared with Figma's (`guide_snap_tests`) |
 | Ctrl to suspend snapping while dragging (macOS) | done | Control on macOS (Cmd keeps working), Ctrl elsewhere; moving, resizing and drawing |
