It’s sometimes handy to point people in the direction of a specific discussion topic or chat channel.
You can do that. Start by typing with a “#” and you’ll see a search box appear.
For example:
This is the 
Announcements topic. Notice the folder icon at the start of it.
And this is a chat channel: 
Daily Check-in . Notice the chat icon at the start of it.
In some cases, there is a discussion topic and a chat channel: For example: 
New to Testing (discussion topic) and New to Testing (chat channel).
Plus you can also search with a “#” to add a tag. For example, here’s an automation tag. Notice the tag icon.
All of them are now selectable so you can jump straight to a discussion topic, chat channel or tag.
