If you mean while in the S Note app. Open a new note, in the bottom right corner next to the settings wheel you should see a hand Make sure you touch that icon to remove the circle with a slash off of it and that allows free hand note taking. Then at the top of the note touch the T icon wiht the line under it and that will bring up your keyboard so that you can swipe or enter your notes by texting on the keyboard.
As far as action memo is concerned, I think this is an S pen specific app and I haven't found a way to enter text in the fashion you have asked. Hope this helps.
