### Step 4: Zooming In Left click the left mouse button, somewhere over the explorer window. While holding it down, drag it to the side to create a zoom box.
Now click the button again, holding it down, to ‘pick up’ the box. Move the box over an area of the design that looks interesting. Double click inside the box and wait while Fractopia zooms in to the area you have selected. (Or left click outside the box if you want to start again).
You can keep zooming in this way to journey deeper and deeper into the fractal. To zoom *out*, hold down the Control key as you double click.
