Fragment Animations

Reveal content step-by-step using fragment markers. Add  after any element to make it appear on the next arrow key press:

## Key Features

- First point appears <!-- .fragment -->
- Then the second <!-- .fragment -->
- And finally the third! <!-- .fragment -->

Animation Types

Specify an animation style after .fragment:

- Fade in (default) <!-- .fragment fade -->
- Slide up from below <!-- .fragment slide-up -->
- Slide in from right <!-- .fragment slide-left -->
- Zoom in <!-- .fragment zoom -->
- Dimmed, then highlighted <!-- .fragment highlight -->

Animation	Effect
`fade`	Fade in (default)
`slide-up`	Slide up from below
`slide-left`	Slide in from the right
`zoom`	Zoom in from smaller
`highlight`	Visible but dimmed, then highlighted

Fragments work on list items, paragraphs, headings, and block elements. The syntax is compatible with Reveal.js.

Speaker Notes

Add speaker notes to any slide using the notes field in YAML frontmatter:

---
notes: |
  Key points to cover:
  - Explain the architecture
  - Show the demo
  - Answer questions
---

# Slide Title

Slide content goes here...

View speaker notes by running Executable Talk: Open Presenter View.

Presentation Options

Customize the presentation using the options field in the deck frontmatter:

---
title: My Presentation
author: Your Name
options:
  toolbar: true                    # Show toolbar (default: true)
  zenMode: true                    # Enter Zen Mode on start (default: true)
  showSlideNumbers: true           # Show slide numbers (default: true)
  showProgress: false              # Show progress bar (default: false)
  fontSize: medium                 # Font size: small, medium, large
  theme: dark                      # Theme: dark, light
---

Toolbar Customization

The floating toolbar can be customized to show only specific buttons:

options:
  toolbar:
    - sidebar      # Toggle Sidebar
    - panel        # Toggle Panel
    - terminal     # Toggle Terminal
    - activityBar  # Toggle Activity Bar
    - zenMode      # Toggle Zen Mode

Set toolbar: false to hide it completely.

Workspace Trust

For security, actions that execute code (terminal.run and debug.start) require Workspace Trust. When opening a presentation with executable actions in an untrusted workspace:

You'll be prompted to confirm before proceeding
Actions requiring trust will show as blocked
You can still use file.open and editor.highlight actions

Requirements

VS Code 1.85.0 or higher
Workspace Trust enabled for terminal.run and debug.start actions

Extension Settings

This extension does not contribute any settings.

Known Issues

Multi-monitor presenter view requires manual command execution (no automatic detection)
Zen Mode state detection is approximate
