The Double Tap - similar to the double click on the mouse, the double tap comes in handy to quickly open a note from the split screen view to the full screen read view. Tap twice anywhere in the Split Screen and the currently displayed note will open in a new Read Screen.
The Swipe - used to navigate to the next or to the previous note. A short horizontal swiping gesture in the Read Screen will display the adjacent note. A swipe to the left will display the next note and a swipe to the right will display the previous note. An "End" message will appear after the first or the last notes in the list.
