Hey community :slight_smile:

I’m looking for a way to autocomplete key names at a specific position in the YAML-Tree.

The following structure is given, where I want the completion to appear:

              EntityName:
                  relations:
                      RelationName:
                          <cursor>

Where is the desired position. Does anyone have an idea, what a matching PlatformPattern could look like?
Thank you!
