Final answer:
To scroll through a document in a Preview window, use the arrow keys for small movements, Page Up/Page Down for page-level scrolling, and Home/End to jump to the start or end of a document. Scroll Lock is not commonly used for scrolling.
Step-by-step explanation:
To scroll through a document in the Preview window, you can use several keys depending on your operating system and application. Generally, the arrow keys allow you to move up, down, left, or right within a document. The Page Up/Page Down keys enable you to quickly scroll up or down by a full page. While the Home/End keys are typically used to jump to the beginning or end of a document, they do not specifically scroll. It is important to note that the Scroll Lock key is not commonly used for scrolling in modern software applications, and its functionality can vary.
On a Mac using Adobe Acrobat, the back and forward functions are achieved with the arrow keys as '←' and '→'. In Mac Preview, '⌘-[' and '⌘-]' can be used to navigate back and forward through previously viewed pages. Some mice, especially those designed for gaming, may have additional buttons that can be programmed to perform forward/backward navigation through a document.
