File > Export > Save for Web (Legacy) (Ctrl/Cmd+Alt+Shift+S) opens a dialog with Original,
Optimized, 2-Up and 4-Up views showing each file's size and download time, and settings for
colour reduction, colours, dither, transparency and matte, interlacing, web snap, lossy GIF,
JPEG quality, the colour table (lock, map to transparent, web shift, sort), image size and
anti-aliasing, Clip to Artboard, sRGB, metadata, slices (all or selected), HTML output and
presets. Preview in Browser opens the HTML page.
Engine: document.exportForWeb, document.exportForWeb.preview (its byte count is the size of
the file Save writes), webExport.settings and webExport.presets.list/save/delete. Saved presets
and the remembered settings are stored in Prefs. Render: quantize_locked, and encode::web for
web snap, colour table edits, lossy GIF and GIF/JPEG comments. PNG files get an sRGB chunk.

The Slice tool (Shift+K) drags out a user slice (Shift square, Alt from the
centre, snapping to ruler guides) as one undo step through
object.slice.create. The Slice Selection tool selects slices (Shift
toggles, object.slice.select), moves them (object.slice.move; object
slices move their objects), resizes a user slice by its handles
(object.slice.setRect), opens Slice Options on a double click and deletes
with Delete (object.slice.delete). Hidden or locked slices can't be
picked. Both tools have cursors drawn in code.

Document.slices holds user slices, Node.slice makes an object an object
slice that follows its bounds, and Document.slices_clip_to_artboard picks
the region auto slices fill (the artboards, or the art and the slices).
Object → Slice: Make, Release, Create from Guides, Create from Selection,
Duplicate, Combine, Divide… (dialog), Delete All, Slice Options… (dialog)
and Clip to Artboard; View → Hide/Lock Slices; Select → Object → Slices;
slice.list reads the numbered layout. The canvas draws the slices in the
Slices preferences' line colour with their numbers.
