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.

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

Alternatively, the 'up' arrow is a shortcut to editing your latest chat message (this only works if the chat input box is empty).

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.

Enter question or answer id or url (and optionally further answer ids/urls from the same question) from

Separate each id/url with a space. No need to list your own answers; they will be imported automatically.
