Edit Expression

This is a quick way to open any expression in an external editor, for easier editing of complex expressions than the expression editor available in After Effects.

1. Select the property with the expression.
2. Click the Edit Expression button.
3. Once you’re done, save the file in the external editor.
4. [Ctrl] + [Click] the Edit Expression button to update it in After Effects.

When the expression is open in the external editor, you can continue editing and saving the expression file as much as you need, and reload it at any time in After Effects.

By default, Duik opens the expression with the default application associated with .js files, but you can set the editor to use: [Shift] + [Click] the Edit Expression button to open the settings.
