When in Mac OS X you can go into the "zoom" mode by accessing System Preferences, select Universal Access and click on the button labeled "Turn On Zoom." You can also find the shortcuts on this screen to quickly turn this option on and off, and to change the amount of magnification.
When you use this feature, you zoom in on the entire screen, including pull down menus, menu bars, etc. You can easily scroll through the screen using the pointer.
On Windows you can try a product called Dragnifier or in Windows XP go to Start — Programs — Accessories — Accessibility — Magnifier. This will magnify the area you are mousing over in a window at the top of the screen.
