You had to hit the enter key 8 times, so it saved you 4 strokes.
Actually, to make a paragraph break with html, since both the opening and closing tag requires that two keys be struck (ctrl + < p ctrl + >), the total # of keystrokes would be 5 per paragraph tag.
If I would have had to manually enter the paragraph breaks, it would require that 20 keystrokes be made minus the 4 double taps of the enter key = 12 keystrokes saved.
Thanks for playing........lol!
