Was writing an email today using Outlook 2013, and had my Surface Pro Type Cover stowed away. So I inked the whole thing. The built-in keyboard widget handled the Subject line, but for the body of the email, inking was direct. Check out the handy menus. Ink tools are built in. Plenty of pens, colors, highlighters, and an eraser. Ruled lines, which will not appear to the recipient. Highlight as needed. Undo button and palm rejection worked perfectly. Use the inking keyboard widget for the Subject line, or type with that keyboard. Note that ruled lines disappear when moving focus away from the Body of the document. View attachment 5665 Colors can be used as highlights. How it looks to the recipient. Nice and clean. And personal.
