Help is available in a number of ways, but the easiest way is by pressing the Help key on your keyboard. The program is great for looking up specific topics of interest as well as for random exploration of its content. Boolean search techniques can be employed. You can print selected text, an entire article, images, or captions. You can also copy text, images, and audio.
Some features are very unMaclike.
The Back button does not take you back to the previous thing that you were doing. To get back to where you last were, you must go to the Features button and click on the appropriate Category button that is displayed.
