I posted a comment in chat that had an obvious spelling error, and realized that I couldn't edit it. No big deal, just post the correction in another comment...but then I saw that I had yet another error (I know, I can barely speak English), and had to post another comment.

SE chat gives a time limit to edit your comments (I think either 2  or 5 minutes, and mods might me able to edit them whenever). How should we handle comment edits? A time limit? No limit at all? Possibility of reading the original comment to avoid misunderstandings and/or arguments? An edit history, in other words.

A five-minute time limit on chat message edits seems reasonable to me.

The two-minute limit on SE chat is a bit too short.

Allowing edits on all messages visible in the current window sounds like an attractive alternative, but it might be misused.

We have implemented this with a 5-minute limit per [Paul's suggestion](https://topanswers.xyz/meta?q=14#a4):

> A five-minute time limit on chat message edits seems reasonable to me.

Click the new button that appears to the right of your message on hover: 

!['edit chat' button](/image?hash=7f0efc8afbbb404eea34b3d5cd8a85c81d04586d55e85e665821608ff75bf7e9)

Alternatively, the 'up' arrow is a shortcut to editing your latest chat message (this only works if the chat input box is empty).
How should "New Chat ™" handle comment edits (if at all)?

@Lamak pinging to let you know we've released the feature and posted an answer here :)
Paul White
Yes, exactly.
Jack Douglas
I think that is the kind of thing @Paul is alluding to by "it might be misused" even if just editing in the current window is allowed
Jack Douglas
I mean someone could change hundreds of chats from months ago in a way that made other people look bad
Jack Douglas
but if the time is unrestricted I can see how the feature might be abused

"there are no comments, only chat"
Jack Douglas replying to GeorgePalacios
that's an excellent question
GeorgePalacios
I'm trying to remove all assumptiond
GeorgePalacios
If it's simply to chat, I can't see any need to restrict length of time of the comment being up prior to editting. If it is to be audited or has some other relevance, maybe the edit should be limited?
GeorgePalacios
What is the point of chat in the new world?

"an edit history, in other, better words"
Lamak
thanks!
Paul White
Did it for you.
Paul White replying to Lamak
You can edit the question to make that clear?
Lamak
Ah sorry, yeah, that's what I meant
Jack Douglas
I think you are just suggesting there is a way to view history?
Jack Douglas
@Lamak please see Paul's comment above. 
Paul White replying to Jack Douglas
great thanks
Jack Douglas replying to Paul White
thanks, fixed!
Paul White
That answer was not submitted by Lamak by the way!
Paul White
That third line shouldn't be part of the quote.  
If only I could edit it 🙂
Paul White
Can you clarify what is meant by:  
> Possibility of reading the original comment to avoid misunderstandings and/or arguments?  
I can't tell what this is suggesting.
