Highlighting important pieces
You can send lengthy emails and PDFs, but don’t nobody got time to read all of that! If you only want to highlight specific parts in your document with a red circle, magnifying window, or text overlay, you can do so with your iPhone.
To highlight certain parts of a document or picture attachment, just open the file up and move your finger to the pencil icon on the top-right corner, then choose any of the available actions. You can find additional options by pressing on the + symbol. Just don’t go overboard when putting in certain highlights since you’ll only end up confusing the reader.
