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 68% (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 |
| Media playback with controls, play across slides, full-screen video | yes | yes | Seeks and loops preserve new-generation video frames and end-of-stream; queue regression and repeated seeks across H.264/HEVC/VP9/AV1 in crates/media. WMA/WMV not decodable |
| Media playback with controls, play across slides, full-screen video, Play/Pause/Stop in the click sequence | yes | yes | WMA/WMV not decodable; click sequence since #116 |
| Animated GIFs play; pause from their corner button | yes | yes (#39) | |
| Media playback with controls, play across slides, full-screen video | yes | yes | WMA/WMV not decodable. Slide Show ▸ Show Media Controls (on by default) hides the playback bar |
| Animated GIFs play; pause from their corner button | yes | yes (#39) | The corner button hides with Show Media Controls |
| See All Slides grid during the show | yes | no | |
| Zoom into part of a slide during the show | yes | no | |
| See All Slides grid during the show | yes | yes: G, or All on the show bar and in presenter view; click a thumbnail, Esc closes the grid | Hidden slides are labelled; the first 48 slides are shown |
| Zoom into part of a slide during the show | yes | yes: Z, then click the slide (or the presenter slide); 2×, Esc or another click leaves it | The presenter keeps the whole slide and draws a frame on the zoomed part |
| 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 | yes in the show | Cmd/Ctrl+L and the on-screen button draw the show's laser colour and leave no ink. The presenter window does not move that dot |
| 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 |

Pausing the timer does not pause the show, animations or rehearsal |
| Slide counter, previous/next/end buttons | yes | yes | |
| Keyboard navigation while Presenter View has focus | yes | yes | Shares the audience window's key handling; handled keys are consumed before buttons, and the presenter stays available at the end screen |

| 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 | |
| Notes font size, scrolling | yes | yes: A- / A+ (and [ / ]), 12–48 pt in steps of 4, default 18; the notes scroll |
|
| Placed on the presenter's display automatically, show on the projector | yes | no: opens wherever the OS puts it | Open PR #433 places the show on a second display when one is attached. This change does not |
| Swap displays | yes | no | Still open on #433 |
| Pen, laser, black screen, zoom from presenter view | yes | Black, White and Zoom buttons; the audience zoom is framed on the presenter slide | Pen and the laser pointer are still keys only; there is no laser yet |
| See all slides from presenter view | yes | yes: All slides opens the grid on the show | |

Rehearse and record

| 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 |
| Highlighter, eraser, keep-annotations prompt, laser from presenter view | 2–4 |
| See All Slides and zoom during the show | 2–3 |
| Presenter view on the right display and a swap-displays command | 2–4 |
| Laser pointer, highlighter, eraser, keep-annotations prompt | 2–4 |
| Record slide show with narration (no camera) | 5–8 |
| Total | ~9–16 (the slide-show row of the feature table carries 10–16 h; recording overlaps the Media row) |
Revision history
| Date | Change | Summary |
|---|---|---|
| 2026-10-13 | minor | Click handling for interactive decks: triggers, per-slide state kept across visits, visible-shape hit testing with hand cursor, advance on click |
| 2026-10-13 | minor | Video seek handoff no longer discards freshly decoded frames or end-of-stream (upstream #416); deterministic queue and four-codec seek regression tests |
| 2026-10-14 | minor | Presenter View handles slideshow keys in its own viewport, including returning from the end screen and Escape; regression tests cover navigation and avoiding duplicate button activation |
| 2026-10-11 | minor | Media effects (Play, Pause, Stop) in the click sequence play with their step (#116) |
| 2026-10-13 | minor | The show has a laser pointer (Cmd/Ctrl+L, the show's laser colour, no ink). Presenter view still does not drive it |
| 2026-10-14 | trivial | Show Media Controls hides the show's playback bar and GIF button |
| 2026-10-14 | minor | Presenter view pauses and resets its timer (T, R) and changes notes size (A-/A+, brackets). The clock shows local time. Second-display placement and swap stay with #433. Checklist breadth stays 66% |
| 2026-10-14 | minor | See All Slides (G) and click-to-zoom (Z) during the show. Presenter view opens that grid and sets black, white and zoom. Checklist breadth stays 66% |
| 2026-10-10 | major | Created: show, presenter view, rehearse and record, compared with PowerPoint 16.113's Slide Show tab and menu |
