When starting a conversation or sharing news from your Newsfeed, hitting enter on your keyboard posts the update instead of inserting a line between 2 sentences. This can get very annoying when you’re trying to post a neat conversation.
Click SHIFT + ENTER to make line breaks. (This works in Facebook too by the way when replying to posts).
Links are longer in SharePoint 2013. (So much for all our clean link management in SharePoint 2010 hey…).
