  65.     You will probably have it happen many times that you need to place
  66.     something in an image very precisely, and find that it is not easy to do
  67.     using a mouse. Often you can get better results by using the arrow keys on
  68.     the keyboard (which move the affected object one pixel at a time, or 25
  69.     pixels if you hold down the <span class="keycap"><strong>Shift</strong></span>
  70.     key), but GIMP also provides you with two other aids to make positioning
  71.     easier: grids and guides.

  124.       The default grid appearance, set up when you install GIMP, consists of
  125.       plus-shaped black crosshairs at the grid line intersections, with grid
  126.       lines spaced every 10 pixels both vertically and horizontally. You can
