Structure

The Structure window shows the structure of the file that's selected in the editing area or in the Project tool window.

It displays something only when the file is recognized as structured. This happens with:

• Rules files
• JSON files
• XML files

In the case of rules files, detected elements are marked as in the following table.

Icon	Description
	Categorization rule
	Extraction rule
	Tagging rule
	Segmentation rule
	Configuration element

Toolbar

Icon	Name	Description
	Sort Alphabetically	Show the elements in alphabetical order.
	Navigate with Single Click	Toggle switch. When selected, a single click on an element is sufficient to jump to the source code line where the reminder is defined, otherwise the same action is triggered by a double-click.
	Always Select Opened Element	Toggle switch. When selected, a single click on an element in the editing area jumps to the corresponding element in the Structure tool window.
	Expand All	Expand the file structure
	Collapse All	Collapse the file structure

Context menu

The context menu contains only IntelliJ IDEA commands, so please refer to its documentation.
Particularly interesting is the Jump to Source command (keyboard shortcut: F4). It moves the focus to the line of source code where the element is defined.

Mouse commands

Double-clicking—or simply clicking, if Navigate with Single Click is selected on the toolbar—a structure element allows to jump to the corresponding line inside the file.

Popup menu

Popup menu (keyboard shortcut: Alt+Ins) allows creating a new project file whose type is consistent with the context.
