I think you're right. The Surface headphone jack has contacts for stereo headphones and a mono mic. Like iPhone earbuds. That adapter you mentioned is what you need to get mic towork in the jack. View attachment 5075
How are you able to save a portion of the screen like this @ScottyS ? I can double tap the top of the pen to take a screen shot and then select the area, but then it inserts it into Onenote. Is there a way you're saving just the selected are as an image? Thanks
You can take a screenshot of just the active window when a (real) keyboard is attached by pressing Alt+Print Screen, or use the Snipping Tool or Send To OneNote to click and drag your selection. But to ink the image the easiest is to insert it into OneNote (or other image editing app that supports pen drawing) and then use Snipping Tool to recopy the image+ink to clipboard.
