I hope this example shows why autocomplete would be useful beyond the comfort of the commenter:

I recently had an issue where someone edited a post (which I'm not the author of) only to add one extra line of indentation to a snippet, which made the post less readable and correct. Even though this example is not very urgent the point holds true.

While one peer reviewer noticed and rejected the edit, it still got approved.

I cannot rollback the edit, so I have two options:

  • Counteredit: Undo the edit manually by editing. This seems like a very bad practice to me.
  • Ping the editor: Ping the editor and ask him to do a rollback.

After trying to ping the editor and realizing that autocomplete does not work (and therefore assuming editors cannot be pinged), I proceeded by flagging the post for moderator attention (first time I used this flag - since it seemed like the only valid option left).
In hindsight this was obviously unnecessary, since editors can be pinged as stated here.


Autocomplete for pinging is a very important feature, because it is the only feedback a commenter gets for whether or not the ping acctually works (and also makes it way easier to ping people with complicated names). So I don't see a reason why this would not be implemented for all pings.

No autocomplete also implies that the ping is going to 'fail'. In case it is intentional to keep users from pinging editors, I see it as very poor security through obscurity. It even pushes users to actions, that are less appropriate (as the example above shows).

Not sure if this is a bug or a feature to be requested. If I am missing something let me know.

    @AnneDaunted Thanks, very informative. I still think that user feedback / transparency is more important, then trying to discourage users by obscurity. A solution as proposed here might be a compromise, but it seems like it has been implicitly declined. I don't think complexity is an issue here.

    A moderator flag would have actually been better here, since moderators can override the approval of the edit (provided no one else edited it later). Pinging the editor won't accomplish much. Sep 3, 2019 at 21:25

    @SonictheAnonymousHedgehog Good point, my decision on what action is best, was based on many unknowns: Does a moderator care (since this is a minor issue)? | Does the editor get informed (so he doesn't repeat his mistake)? | What actions can a moderator take?. I'm going to read up on these a bit more.
