-### Jumping between unresolved threads (deprecated)
-
-> - [Deprecated](https://gitlab.com/gitlab-org/gitlab/-/issues/199718) in GitLab 13.3.
-> - This button's removal is behind a feature flag enabled by default.
-> - For GitLab self-managed instances, GitLab administrators with access to the
-  [GitLab Rails console](../../administration/feature_flags.md) can opt to disable it by running
-  `Feature.disable(:hide_jump_to_next_unresolved_in_threads)` (for the instance) or
-  `Feature.disable(:hide_jump_to_next_unresolved_in_threads, Project.find(<project id>))`
-  (per project.) **(CORE ONLY)**
-
-When a merge request has a large number of comments it can be difficult to track
-what remains unresolved. You can jump between unresolved threads with the
-Jump button next to the Reply field on a thread.
-
-You can also use keyboard shortcuts to navigate among threads:
-
-- Use <kbd>n</kbd> to jump to the next unresolved thread.
-- Use <kbd>p</kbd> to jump to the previous unresolved thread.

 ### Marking a comment or thread as resolved
 
 You can mark a thread as resolved by clicking the **Resolve thread**
