How can you access a list of Appian functions?

Accessing a list of Appian functions can indeed be achieved by using the expression editor. When you type "fun" in the editor, it triggers the auto-complete feature, which presents a list of available functions. This feature is designed to aid developers by providing quick access to functions, making it easier to discover and utilize them efficiently while building applications.

While other methods may seem attractive, they don't directly provide the kind of immediate integration and assistance that typing "fun" does within the expression editor. The lightbulb icon in the expression editor is useful for providing explanations and example usages of functions, but it does not present a list in the same way. Clicking on a toolbar button specifically for viewing functions might not be a standard feature in all versions of the editor. Finally, checking docs.appian.com offers comprehensive documentation but requires navigating away from the editing environment, which could disrupt the workflow when creating expressions.

That's why typing "fun" directly in the expression editor is a practical and efficient way to access functions in Appian.
