How to use home and end keys

To right-click on something, hold the control key and then click an item to get a right-click context menu. This is how you can customize Firefox on your Macintosh machine.

The page up and page down actions are accessed by holding the fn key and then pressing the up and down arrow keys. Home and End are the left and right arrow keys whilst holding the fn key down.

How to take screenshots

Press Shift-⌘-4 to take a screenshot. A cross-hair will appear. Drag a square around the area that is to be captured; then release to capture a PNG format image to the desktop.

Press the Shift-⌘-3 keyboard shortcut to take a screenshot of the entire screen and save it in your ~/Desktop directory.

If it is desired to capture a single window, press Shift-⌘-4, then the spacebar. Hover over a window to select it, then click to screenshot the window. Very simple.
