For questions about the "Linked" sidebar on questions, a selection of other questions that the question links to, or other questions that link to that one. This tag can also be used for the linked questions pages, which show all such questions.
The "Linked" sidebar on questions is a list of other questions that the question links to, or other questions that link to that one. Questions can be populated there from links in the question body and in answers, as well as any comments on the question or its answers. Additionally, questions closed as duplicates of the current question are listed there, as is the duplicate target if the current question is closed as a duplicate.
The sidebar only consists of a selection of linked questions, but you can access a full list of linked questions by clicking "see more linked questions" (if the list is truncated).
