AL Outline View
Working with the AL Language extension you have access to the Outline view. The Outline view is a separate section in the lower left corner, right under the Explorer view.
The Outline view is enabled by default and shows the symbol tree of the currently active cursor, it also allows you to filter as you type. Double-clicking on any node makes your cursor jump to the selected definition or keyword. The Outline view will also display any errors in your project for easy inspection.
You manage the look and feel of the Outline view by defining a number of settings, that are all enabled by default:
outline.icons- Outline elements displayed with icons.
outline.problems.enabled- Show errors and warnings on outline elements.
outline.problems.badges- Badges displayed for errors and warnings.
outline.problems.colors- Colors used for errors and warnings.
