Claude 887ea1e706 Slide show: click-triggered animations, per-slide state and hit testing
Make the slide show behave like PowerPoint for interactive decks.

- Hit testing resolves the topmost visible shape under the pointer.
  Non-interactive shapes block shapes beneath them; the hand cursor
  shows only over interactive shapes.
- Click-triggered animations (interactive sequences) play on shape
  click, repeat after their last step, and apply in click order so
  cycling "score ring" shapes work.
- Each slide keeps its own progress: returning to a slide through a
  link or Back restores hidden shapes and animation state.
- A shape with a link and an animation follows the link immediately;
  its animation clock only runs while the slide is shown and resumes
  with the remaining time on return.
- With advance-on-click off, background clicks still play animation
  steps but never change slide.
- A click on a playing step completes it at once.

Docs (gaps, animation and slide show parity, roadmap) are updated.

Slide show and presenter view: parity with PowerPoint

Last reviewed: 2026-10-10 · Last updated: 2026-10-13 · Change: minor (interactive-deck clicks in the slide show; previous: major (created; measured from crates/ui-egui/src/show.rs and crates/anim/src/show.rs against PowerPoint 16.113's Slide Show tab and menu)) · Target: Microsoft PowerPoint for Mac 16.113 (Microsoft 365)

Presenting is the job PowerPoint is hired for. This doc covers the show window, presenter view, rehearsal and recording. Transition and animation playback are in animation-parity.md; display hardware in hardware-parity.md. Area score: checklist breadth 66% (measured), ~60% ready (estimated), 10–16 h to parity.

Running the show

Feature PowerPoint DeckCraft Notes
Play from Start / from Current Slide (F5, Shift+F5, Cmd+Enter) yes yes
Next/previous by click, arrows, Space, Page Up/Down, Enter, Backspace yes yes #17 reported arrows not working in v0.3.0 AppImage; recheck
Go to slide (number + Enter), first/last yes yes
Black / white screen (B / W) yes yes
End screen, Esc to leave yes yes
Step clock: a click after a long pause plays its step (#11) yes yes
Hidden slides skipped yes yes
Hyperlinks and action settings followed (slides, web, mail, End Show, Last Viewed) yes yes Only http(s) and mailto open outside the show, by design (safe_url)
A shape with a triggered animation plays it when clicked; shapes an animation has hidden cannot be clicked; a shape without an action on top of one with an action blocks it; the pointer is a hand over what can be clicked yes yes Click boxes are bounding boxes; "play sound" actions (ppaction://media) do nothing yet
A slide the show returns to (link, arrow keys) looks as it was left; a triggered animation goes on where it stopped yes yes A main-sequence step still playing when the show leaves is finished
"Advance on click" off: a click never leaves the slide (animation steps still play, keys still move on) yes yes
Media playback with controls, play across slides, full-screen video yes yes WMA/WMV not decodable
Animated GIFs play; pause from their corner button yes yes (#39)
See All Slides grid during the show yes no
Zoom into part of a slide during the show yes no
Pen and highlighter ink yes pen only (Cmd+P pen, Cmd+A arrow, E erases all ink) No highlighter, per-stroke eraser, ink colours, or keep/discard annotations prompt
Laser pointer yes no 1–2 h
Subtitles and live captions yes (cloud speech) no AI dimension
Custom shows yes yes
Set Up Show: loop until Esc, kiosk (browsed at a kiosk), show without animation/narration, pen colour, slides range yes yes, most options
Use rehearsed timings yes yes

Presenter view

Feature PowerPoint DeckCraft Notes
Separate presenter window with current slide, next slide, notes yes yes (an egui viewport, 1100×700)
Elapsed timer yes yes
Pause / reset timer, clock yes no
Slide counter, previous/next/end buttons yes yes
Notes font size, scrolling yes scrolling only
Placed on the presenter's display automatically, show on the projector yes no: opens wherever the OS puts it Beta blocker, 3–5 h
Swap displays yes no
Pen, laser, black screen, zoom from presenter view yes keys only
See all slides from presenter view yes no
Rehearse with Coach (Speaker Coach) yes (cloud) no AI dimension

Rehearse and record

Feature PowerPoint DeckCraft
Rehearse Timings, keep timings yes yes
Record Slide Show (narration, ink, laser, camera; Cameo) yes no
Clear timing / narration yes timings only
Export the recorded show to video yes no (see file-format-parity.md)

Reading View

Reading View in a window with navigation: present (checklist row done).

Estimates

Work Hours
Presenter view on the right display, swap displays, pause/reset timer, clock, notes size 3–5
Laser pointer, highlighter, eraser, keep-annotations prompt 2–4
See All Slides and zoom during the show 2–3
Record slide show with narration (no camera) 5–8
Total ~12–20 (the slide-show row of the feature table carries 10–16 h; recording overlaps the Media row)
