Across the Stack Exchange network you may leave comments on a question or answer.  How do comments work? What are comments for, and when shouldn't I comment? Who can post comments? Who can edit comments? How can I format and link in comments? My comment doesn't contain some of the text I typed in it; why? My comment appears to be long enough, but I can't post it because it's too short; why? Who can delete comments? When should comments be deleted? Why can't I comment on specific posts even if I have enough reputation to comment? When can comments be undeleted? What are automatic comments? How can I link to comments? Anything else I should know about comments?  Also see the FAQ articles on  and .

Once in a while you wish to address a comment to someone in particular, so you type @ and then you pause ... because the username is  or .  Short of using copy-paste to get their username right (which is even more cumbersome on a mobile device), is there another way around this? In a few cases I've noticed that the system will attempt to "promote" a comment to a reply, but I'm not sure if that's very reliable.  Should user names at least start with a normal letter?  Update  The auto-complete feature seems to normalize Zalgo'ish usernames, so typing the letter L will trigger the suggestions as expected; this is of course knowing that the name actually spells "lawrence", which may not always be obvious.  Knowing the way of the symbol ninja would surely help to type Ω using only the elbows as well, but not everyone is blessed with the same keyboard layout.  Suggestion  It would be nice to have a reply feature like this:        When ↳ reply is clicked, it will automatically populate the comment box with @username pre-filled in.   Additional notes  To clarify, I'm not suggesting to put the "reply" on all comments, as proposed , because in most cases the owner of a post is already notified of a new comment; this would strictly be to effect cross-commenter communication.

When you click the add a comment button when you don't have enough rep, you get a pop-up saying that you need more rep in able to comment. Except, it is too far away and users might be confused for a while before realizing the pop-up is on the other side of the page:     Clearly, that is very inconvenient for a lot of people, like me. Can we move the pop-up to be right next to the add a comment button?

I'm very often in the situation of having to link to another post (mostly questions) from comments. As moderator of , I often link to related or duplicate questions. I can't use the "close as duplicate" feature to add such links automatically because of my moderator status, as long as I don't want to close the question immediately.  Now, I find it good style to have the link in the form of [post title](http://posturl), not just http://posturl. A comment like "Related question: Foo baz bar" is simply more readable and informative than "Related question: http://xyz.stackexchange.com/q/1235/6789". Unfortunately, pasting the URL into the comment doesn't convert it to this format automatically, as is done for questions and answers.  has already been declined.  At the moment, I manually mark and copy the question title to the URL bar of my browser and add the required [ ] and ( ) (and with the new Firefox version also the http:// :-( ) and then copy the whole thing to the other question.  I'd like to suggest the following feature: In addition to the existing 'share' button below every post, there could be another one which instead provides the required format [post title](http://posturl). This way a question can be linked to quickly from a comment or as part of a chat message. Answer posts can have the same button which could either still use the question title (but answer URL) or add a "Answer to " or similar in front of the title.   This feature should be easy to implement (maybe as a greasemonkey script) while avoiding the drawbacks of an automated conversion mentioned in the accepted answer of the above linked feature-request.

Consider the example below. Using \hyperref[hello]{go to hello} I can jump to last page but I cant find the way to hyperlink back to where I was (before i clicked) unless I scrolled back manually. My question is: Is there a way to jump to a hyperlink and jump back to the text in latex? Footnote seems to have that functionality by creating a little blue arrow next to the footnote. Is there anything similar for hyperlinks?  \documentclass{article} \usepackage(hyperref) \begin{document}   \SweaveOpts{concordance=TRUE}  \hyperref[hello]{go to hello} \newpage  bla bla  \newpage  bla again  \newpage  hi  \label{hello}   \end{document}

While commenting on posts, when we start typing @ and a few characters that match one of the earlier commentators, a suggestion appears above the comment text area. Is there a shortcut to accept that suggestion?

If I click "add comment", the comment hint (placeholder; "Request clarification or add information.") is not a hint, but editable text. If I delete the text and click outside of the comment then the hint appears as it should and when I click back into the comment box the hint disappears as it should.   I am on Internet Explorer 10.0.7.  Am I just oblivious and this is how it has always been (having to delete the comment hint), or is this a bug?

In questions, links get converted into question titles (see )  Can the same functionality be added to comments?

I understand that there is an upper limit. But why do you have to type at least 15 characters to post a comment? It is easy to work around it anyway (like adding dots or other useless things).

The conversation often continues in the Comments and important information is held in the comments. I'd like to have threaded comments there.

How can I format the code in comments?

I'm trying to post a sample of code that looks like this:        Look at all of those comments, and it still won't allow me post! What am I doing wrong?

I'm using the hyperref package in my document to provide hyperlinks to external documents. However, I don't want to have the links coloured or underlined, because I find this usually ugly and distracting. What I would rather like is a little symbol beside the link text to provide a small hint for the reader that there is something clickable. What I have in mind is something like the little symbol constisting of a small square and an arrow you can find e.g. in Wikipedia for external links. Is there any package or font that provides such a symbol or do I have to brew one myself?

Is there anyway by which I can comment out a word within a sentence?

I've noticed that since a few days (weeks?), the "Show n more comments" link at the bottom of the comment chain does not disappear after clicking. The comments are correctly loaded, the link just doesn't disappear (and upon click, a new network request is initiated again).  This happens on every site in the Stack Exchange network when you're not logged in for the website.  To verify this bug, just open an incognito window and pick a post with lots of comments.

It often happens that people will refer to other questions by simply pasting the full link to this question, especially on Meta.  Would it be a good idea to detect such links, and replace them directly by a formatted link on their current title?  Example:    You can try formatting at this  question:  https://meta.stackexchange.com/questions/49424/stack-exchange-sandbox   Would be automatically changed in:      You can try formatting at this   question:    It would make links given by new users (unaware of the full syntax) more elegant, and it would also be faster when more regular (and lazy) users want to point to another question without making the usual "see it "    Edit: Note that this behaviour is implemented already for the "possible duplicate" auto comments, so the question here is not about "how to do this technically".
