This AppleScript creates a countdown timer in Keynote using a user-specified duration and a styled base slide.
- An open Keynote document with a single base slide.
- Style the Base Slide: Ensure the base slide contains a single text field as the timer placeholder.
- Execute the Script: Run the AppleScript.
- Input Duration: Provide the countdown duration in seconds.
- Generate and Export: After slide creation, export the presentation as a movie, setting each slide to last one second.
Providing 60
as input will generate 61 slides, counting down from 01:00
to 00:00
.
To avoid unintended duplications, the base slide should only contain the timer placeholder - a text field set with your preferred font style.
