How can I link to a specific comment on drupal.org? I'm aware that you can use [#1234] syntax in posts on drupal.org issue pages.

However, is there any syntax to point to the specific comment, like: [#1234:12]?

I was using it before, but I forgot the syntax and I can't find it anywhere.
References to project issues in the form of [#1234] (or [#1234-2] for comments) turn into links automatically


That is from the very bottom of compose tips.

So just replace the colon with a hyphen and your guess would have been perfect.
