When reviewing answers in the Low quality posts review queue there seems like there should be an option for other action instead of just looks okay, edit, and delete/recommend deletion. I am asking this as I run into answers from time to time that while they don't look okay do not rise to the level of deletion. Having this option would allow for better handling of questions that don't fit into any category and the reviewer doesn't have what they need to edit it into proper shape.
- Choose Looks OK for questions that are on-topic, sufficiently detailed, and not too broad. Use this option for answers that answer the question as asked, even if they may be incorrect.
- Select Edit if the post is good quality, but you can improve the post to make it better. Avoid editing posts that should be closed or deleted, as it will remove the post from review.
- Recommend deletion or Delete if you think that an answer does not address the question at all, is link-only, or is incomprehensible. Do not vote to delete answers that are simply wrong. You may leave a comment explaining the issues with the answer, or choose one of the provided canned comments.
- Recommend close or Close if you think that a question should be closed (See What does it mean if a question is “closed”?).
- Skip if you’re unsure about the post’s quality.
I agree that the "Looks OK" guidance for answers is a bit vague and might lead some people to think that choosing that option means they think the answer is acceptable quality. There is more detailed information in the FAQ Guidelines for reviewing Low quality posts / Low quality answers, that is linked to the help topic. (I'm not sure if it's linked somewhere it can be found while reviewing.) It would also be helpful if the help topic explained explicitly what the low quality queue is for, not just how posts get into it.
The entire purpose of that queue is to figure out whether to delete/close or try to salvage low quality posts. If you don't want to say it looks OK, and you don't want to delete it, and you can't think of a way to salvage it through editing, just skip it (maybe leave a comment if you think it would be helpful).
What else would you want to do to it that should remove it from the queue? I don't think leaving a comment should remove it from the queue; if you think the author is still engaged with the post and could salvage it with a minor edit, then you should leave the comment and say "Looks OK". Deletion is only for content that can't be edited to be acceptable quality. It is not for incorrect answers. If extensive edits are required to bring a post up to quality, it's probably better to delete it. It doesn't prevent the author from posting a better answer unless they have a habit of posting low quality answers.
If it helps, think of the options this way:
Looks OK → "Doesn't need to be deleted or closed"
Edit → "I can fix it so it doesn't need to be deleted or closed"
Delete → "Needs to be deleted"
Skip → "I'm not sure or I don't want to make a decision on this post"
