Let me start with the way most people quote text in Teams.
After highlighting the text and copying it (Ctrl + C).
Now you can paste from your clipboard (be sure to use Windows + V!).
Here’s the shortcut though. Instead of all of that clicking, just type “> “ (the space at the end is key!) and the Quote field will appear.
This saves quite a few steps – especially over the course of a day, and it makes your messages much more readable by providing context to the exact comment you’re replying to.
As of this writing, I hadn’t found a shortcut for a code block (tell me if you know!) – but Teams should add one of those too IMHO.
Also, if you’re using Teams on a mobile device, you can swipe right on a message to quote the message you swiped.
So there you have it, 3 ways to quote text in MS Teams!
