From here: https://github.com/JetBrains/kotlin-web-site/blob/master/pages/community/slackccugl.md One can read:

use “Code or text snippet” available from + menu next to message input

But I don’t find any such +-menu. Anyone know what I’m doing wrong? (Screenshot of what I see will be added to thread ⬇️ )

Slack changed, now you would use the

</>

button to put code inside your message or the leftmost button to attach a file

I might open a PR to fix that, but first I must understand what

Slack supports Kotlin markup

on that page means. I don’t get markup (which I interpret as colored keywords) when I use the

</>

button

Yes, it means it supports Kotlin files when attaching code, not inside messages
