Keynote Countdown Timer Script

Overview

This AppleScript creates a countdown timer in Keynote using a user-specified duration and a styled base slide.

Prerequisites

• An open Keynote document with a single base slide.

Usage

1. Style the Base Slide: Ensure the base slide contains a single text field as the timer placeholder.
2. Execute the Script: Run the AppleScript.
3. Input Duration: Provide the countdown duration in seconds.
4. Generate and Export: After slide creation, export the presentation as a movie, setting each slide to last one second.

Example

Providing 60 as input will generate 61 slides, counting down from 01:00 to 00:00.

Note

To avoid unintended duplications, the base slide should only contain the timer placeholder - a text field set with your preferred font style.
