Hand Tool - Use it to pan around the image previews. The Hand tool only functions in the outlined view when you are in 2-Up or 4-Up mode, but all views will pan to show the same area after you release the mouse button. The same spacebar shortcut for the hand tool where here just as it does in the main Photoshop workspace.
Slice Select Tool - Used for creating slices when you need to cut an image up for your Web page layout. We will not be covering image slicing in this course, but you can learn more about it in my article on Slicing Web Graphics.
Zoom Tool - Use it to zoom in on a preview. You can also use the zoom drop down box at the bottom left of the Save for Web dialog. When you zoom in and out, all your views change to the same zoom level.
Eyedropper Tool - Use it to select individual colors from your image. The eyedropper color is displayed in the color swatch just below the tool button. Like the hand tool, it can only be used in the Outlined view when in 2-Up or 4-Up mode.
Eyedropper Color - Shows the color you last selected with the Eyedropper tool.
Toggle Slices Visibility - Used when working with slices. Not covered in this course.
