Zoom In/Out Tool
Go to the preview window and click the magnifying glass icon 
to initiate the Zoom function. There are four ways to use it:
- First method: Move the mouse to the area that you will use as a beginning point for the area you want to magnify in the preview window, left-click and hold the mouse while dragging across the area you want to enlarge, then release the left button of the mouse.
- Second method to Zoom In: Press and hold the Shift key, and click the mouse. The magnification level will increase according to the following range - 100%, 200%, 400%, 800%, 1600%, 2400%, 3200%, 6400%, and 10000%.
- Third method to Zoom In: Directly click the mouse inside the preview window. Each click magnifies the view to the next preset standard percentage by system default, according to the following range: 50%, 100%, 200%, 400%, 800%, 1600%, 3200%, 6400%, 10000%, 40000%, and 100000%.
- Fourth method to Zoom In: Go directly to the Zoom value pull-down menu and choose from a preset percentage, according to the series of system default percentage values. Click the arrow beside the Zoom tool to display the magnification menu.
You are also able to define the zoom value. You can enter the value preceding the % symbol. If you enter 80, then the system will default to 80%. The value entered will not be saved in the list.
When you press and hold the Zoom Tool, and hold down Alt (Windows) or Option (Mac OS), a minus sign ( - ) appears at the center of the zoom tool. The method for using the Zoom Out tool is the same as the Zoom In tool.
