+==== Improved keyboard navigation in Comments dropdown when inserting `@Mention`
+// #TINY-12785
+
+Previously, typing `@` to open the mentions dropdown list inside the Comments card did not support the **Shift+Enter** keyboard combination. For example, when typing a `@` + navigating to a user in the selected Comment card, pressing **Shift+Enter** did not insert the `@mention` to the `<textarea>` for the comment body.
+
+In {productname} {release-version}, this issue has been resolved by implementing an `onShiftEnter` handler that mirrors the behavior of the regular **Enter** key, ensuring consistent and predictable keyboard interaction when selecting items in the `@mentions` dropdown within comment cards.
