I am also right-handed and agree that it is a bit odd to reach across the screen to type letters. However, that is the logical place to put the keyboard since then it doesn't cover up the puzzle at all. You could certainly move the keyboard to the right side, but you would be minimizing it all the time just to see the puzzle squares. At that point, you would be better off using the default xkbd layout (i.e. the small one in the lower right corner) which covers up only a portion of the puzzle.
