Final answer:
To select an alternative code editing tool, you would click on the red box (External Script Editor) within the settings or preferences of your development software.
Step-by-step explanation:
To choose an alternative code editing tool, you would typically click on the option or setting within your development environment that specifies the editor. For many integrated development environments (IDEs) or other software development tools, this is commonly found in the preferences or settings menus. In this context, the red box (External Script Editor) is most likely where you would click to choose an alternative code editing tool.
This selection allows you to select the editor that you are more comfortable with or that provides specific features you need for your coding tasks. It could range from a simple text editor to a more sophisticated IDE depending on your preference and the support provided by the primary development platform you are using
