Just wrote a comment and did not notice a typo. And comments can not be edited. My suggestion is to allow editing of your comments for a short time after sending, say, 5 minutes. Well, in order to avoid confusion, do not allow editing a comment after someone has answered or voted.
UPD : “Use search,” said an inner voice. Indeed, this topic has already been discussed:
Editing comments . But since we are waiting for
Brave Habr , I will allow myself to raise this topic again.
