Me too! I have been doing it regularly. I’m moving between applications and my brain just fails to switch to “Teams” mode and remember that I’ve got to hit SHIFT+ENTER to get a new line. This leaves me frustrated with posting partial messages (or messages I wish hadn’t been sent as I wasn’t finished).
Solution: Hit the Format button (the first button with an icon of ‘A’)
This hack may be able to help you. It does require some forethought, but I’ve found my brain is having a much better time remembering this than SHIFT+ENTER.
Simply don’t use the standard inline reply box if your message is going to be anything longer than a few words.
By default, the first message extension (just under the inline input area) provides a richer editing experience.
In this editing experience pressing ENTER gives you a new line as you would expect – how novel!
Not only that you will find you can make your messages look a lot better with some of the options available here.
