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
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)
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
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
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)

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)
2026-10-10	major	Created: show, presenter view, rehearse and record, compared with PowerPoint 16.113's Slide Show tab and menu
