Presenting Slides

For everyone

The Presenter View

When you start a live session, Quizzibility enters presenter mode — a full-screen slide view similar to PowerPoint or Google Slides, but with interactive questions and live polling built in. The presenter controls the pace using keyboard shortcuts or the on-screen navigation, while students follow along on their own devices.

Essential Keyboard Shortcuts

Quizzibility's presenter is built on reveal.js, so many shortcuts will feel familiar:

  • Right arrow / Space — Next slide
  • Left arrow — Previous slide
  • Up / Down arrows — Navigate vertical slide stacks (sub-slides within a topic)
  • F — Toggle fullscreen
  • S — Open speaker notes in a separate window
  • H — Toggle high-contrast mode
  • O — Overview mode (see all slides as a grid for quick navigation)
  • B — Black out the screen (useful when you want students to focus on discussion, not slides)
  • Q — Show or hide the session QR code and join code overlay

High Contrast Mode

Pressing H activates high-contrast mode, which switches the slide theme to white text on a dark background with larger fonts and simplified styling. This is designed for rooms with poor projectors, students sitting far from the screen, or anyone who benefits from higher contrast. It works as a toggle — press H again to return to the normal theme. Slides are authored once and rendered in both modes automatically; you do not need to create separate high-contrast versions.

Speaker Notes

Press S to open a speaker notes window. This second window (meant for your laptop screen, not the projector) shows the current slide, your notes, a preview of the next slide, and a timer. Speaker notes are written in the deck editor alongside each slide.

QR Code Display

Press Q or click the QR button to overlay the session's join code and a scannable QR code on top of the current slide. This is typically the first thing you show at the start of class — students scan the code with their phone camera to open quzi.app with the session code pre-filled. The overlay disappears when you press Q again or advance to the next slide.

The Student View

Students do not see the full presenter deck — they see a streamlined interface focused on the current question or activity. When the instructor is on a content slide (no question), students see a waiting screen. When a poll or question goes live, it appears immediately on their device.
