The LevelWindow-Checklist states:
Strg + Linksklick durchführen und Maus bewegen:
- Ggf. passt sich die Range der LevelWindow-Skala an, falls der Balken über die Grenzen hinaus bewegt wird
The range is not automatically expanded / adjusted if the slider is moved out of range.
It is not clear if this is a bug or the feature is not necessary. In the later case the test-action has to be removed from the checklist.
