Presenting a Page as Slides

Any page can double as a slide deck — no separate file, no special format. You write a normal page; Eduskript can project it full-screen, one slide at a time. The page source is the single source of truth: the same content reads as a scrolling page or presents as slides depending on how it's opened.

Starting a presentation

Open a published page and click the Present button (the projector icon, next to the annotation toolbar at the bottom of the screen). The page goes full-screen and shows one slide at a time.

By default the Present button is shown to teachers only — presenting is a teaching action. To let students (and any visitor) present the page too, turn on "Let anyone present this page as slides" in the page editor (see Making a presentation public).

The deck opens on the slide you were scrolled to — scroll to the section you want to start from, then hit Present.

Navigate with:

Action	Keys	On-screen
Next slide	`→` · `Space` · `Page Down`	chevron (right edge)
Previous slide	`←` · `Page Up`	chevron (right edge)
Exit	`Esc`	✕ (top-right)

Interactive components keep working inside a slide — code editors run, quizzes answer, videos play. Typing in an embedded code editor won't flip the slide.

How slides are split

Slides are delimited by the markdown you already write — there's nothing new to learn for the basics:

Marker	What it does	Shows on the page?
`# Heading` / `## Heading`	Starts a new slide (the heading leads the slide)	yes — a normal heading
`---`	Starts a new slide	yes — a horizontal rule
`---/`	Starts a new slide	no — invisible divider
`---x`	Ends the slide and drops the following content from the deck until the next break	no — the text still shows on the page

So a page with ## sections already presents sensibly with zero extra work. Reach for the others when you want finer control:

---/ — split into two slides without drawing a horizontal rule on the scrolling page.
---x — keep long background prose on the page but leave it off the slides, so the deck stays tight. The excluded text reappears on the page (and resumes being deck-eligible) at the next ---, ---/, or heading.

Example
## Photosynthesis
The headline reaction…

---/

## Two stages
- Light reactions
- Calvin cycle

---x

### Teacher notes
Long background reading that students read on the page but that
shouldn't clutter the projected slides.

---

## Recap
This is four slides (Photosynthesis · Two stages · Recap, plus anything before the first heading). The Teacher notes block is on the page but skipped in the deck.

Blank slides are never produced — a divider sitting right before a heading, or two dividers in a row, collapses away.

Drawing on a slide

While presenting, use the pen toolbar at the bottom (same pens, colours, sizes, and eraser as the page annotation toolbar):

Click a pen to draw; click it again to stop (so you can click through to the slide).
Hover a pen for its colour and size popover.
The eraser removes strokes; the trash icon clears the current slide.

Slide drawings are local and temporary — they live only for the duration of the presentation, are kept per slide (switch away and back and they're still there), and are never saved. They are completely separate from the page's annotation system.

Zooming

The zoom control sits below the navigation chevrons on the right edge. Hover the magnifier icon to reveal a slider, then drag to enlarge or shrink the current slide — handy for making a diagram or code snippet readable from the back of the room.

Making a presentation public

In the page editor, tick "Let anyone present this page as slides". With it on, the Present button appears for every visitor, not just logged-in teachers. Leave it off (the default) to keep presenting a teacher-only action while the page itself stays publicly readable.

Exam pages don't offer presentation.
