How Variables Work

Variable Syntax

Variables are wrapped in {{ and }} and follow this pattern:

{{variable name: option1, option2, option3 }}

Predefined Variables

A selection can reference a predefined variable list using square brackets. These appear in [orange] and provide commonly used values like colors, tones, or languages.

{{Tone: [tones] }}

Custom Selection Lists

You can also provide an inline list of choices separated by commas.

{{Format: bullet points, paragraphs, numbered list }}
