The File Structure popup window allows you to get an overview of all the elements defined in a file or a package.

You can use it to navigate to any definition and invoke it from anywhere.

How to use:

Use ⌘F12 (macOS) / Ctrl+F12 (Windows/Linux), and a window with all the elements defined in the current file will show up.

Pro tip:

Press ⌘F12 (macOS) / Ctrl+F12 (Windows/Linux), again with the window still open, and it will show all the elements defined in the package of the current file.

Speed Typing can then help you to narrow down the list of elements to the one that you need.
