4. RETENTION *scratch-comments-retention*
Comments go away when the buffer is deleted (|:bdelete|, |:bwipeout|) or when
you run |:CommentClear|. Exporting leaves them in place, so you can export as
often as you like. To keep comments, save an export to a file.
Closing, unloading or wiping a buffer does not delete its comments. They
remain in memory with their last location and snippet until you delete them,
run |:CommentClear|, or exit Neovim. Exporting leaves them in place. Save an
export to a file if you need to keep comments after exiting Neovim.
If you delete all the lines a comment is on, the comment becomes an orphan.
Orphans are listed last in |:CommentList| and in an "Orphaned" section of the
export, and |undo| restores them. To delete one, run |:CommentDelete| on a
line with no comment.
When the same source is reopened, signs return if the saved text still occupies
the same range. Comments are not automatically moved to other lines. For
asynchronously loaded sources, a comment may remain active without a sign
until its text arrives; an incomplete load is not treated as an orphan.
If you delete all the lines a comment is on, the comment becomes inactive (an
orphan). A completed ordinary file reload with mismatched text also makes a
parked comment inactive. Inactive comments are listed last in |:CommentList|
and in an "Orphaned" section of the export; |undo| restores an extmark whose
buffer is still present. Delete an inactive comment with |:CommentDelete|
from the built-in quickfix list or its open card, or open it with |:Comment|
and save it empty.
