Presenting a deck

The presenter is the browser page inkflow serve opens, and it is the same page an exported build produces. Everything on this page works in both.

Press ? at any time for the full keybinding list.

Esc closes whatever is open. With nothing open it resets the zoom.

Moving around

Steps versus slides. → advances the build on the current slide and moves on once it is finished. ↓ skips straight to the next slide. Use ↓ when you are running short on a slide you have already made your point on.

The picker (g) is a search box over slide titles. Type a few letters, or a slide number, and press Enter. Matching is fuzzy, so arc finds "Architecture overview". It jumps to that slide with its build already complete, which is what you want when someone asks about an earlier diagram.

The overview (o) shows the whole deck as a thumbnail grid. Arrow keys move the selection, Enter opens the highlighted slide, and o or Esc returns without moving.

Drawing attention

The laser (.) replaces the cursor with a dot. Drag and it leaves a trail that fades on its own, so you can circle a term or underline a line of code without leaving anything behind. Press . again to go back to the normal cursor.

Zoom magnifies part of a slide. Hold Ctrl and scroll to zoom toward the pointer, or drag to pan. +, - and 0 do the same from the keyboard.

Zoom is local to the window. A second screen or a following window keeps its own view, so magnifying a detail on your laptop does not disturb the projector. Navigating while zoomed eases back to the full slide first.

Note

This is the presenter's camera, unrelated to the Zoom transition.

Blackout and whiteout (b / w) cover the slide with a solid colour. Use them when the audience should be looking at you, or at a demo, rather than at the screen. Any key brings the slide back.

Adjusting the view

Dark and light (t) switches the palette when the theme provides both. Every element painted with a token class follows. Useful when the projector washes out a dark deck.

The presenter panel (p) opens speaker notes, a next-slide preview and timers in a sidebar. It has its own page.

Diagnostics (d) shows the warnings from the last rebuild, which is where a missing font or an unresolvable image reference appears. A banner surfaces automatically when new ones arrive under inkflow serve.

Notifications (n) lists recent transient messages after their toast has gone.

Touch and mobile

On a touchscreen, swipe left and right to move between slides, or tap the left and right edges of the stage.

A floating control appears with buttons for dark/light, the step indicator and fullscreen.

Where you are in the deck

The status bar carries the slide number, a ring showing progress through the current slide's steps, and buttons for the overview, the presenter panel, sync mode and fullscreen.

Under inkflow serve it also has an Edit button for jumping to a slide's source.

The position also lives in the URL as #slide=7&steps=2. Copy the link to send someone a specific slide, and a refresh keeps you where you were rather than jumping to the start.
