I’m not quite sure if this is a bug, something yet to come, or something for the wishlist forum when it comes about, but I’ve notice that, while typing in a document, the only word count available is the total count. When you highlight something (i.e. click and drag your mouse over the text or shift and arrow key it) it doesn’t have a separate word count for that highlighted phrase.
Now, I couldn’t find anything in the tutorial that spoke about this, so I decided to make a post here, just in case it was a bug. And if it isn’t, I will be recommending the option, because it can be useful sometimes.
