Short description of error:
Throughout Blender's user interface there is a few places where the tooltip says "Undocumented operator". Here's a list of a few I've found in the outliner:
Right click on a collection or object and in the pop up, these operators are undocumented:
Unlink All the options in the "ID Data" section.
I will try an keep an eye out for more of these to help polish 2.83 for the LTS release.
Also thank you everyone who has worked on the Blender project.
