This book uses the following conventions to describe the actions you perform when using the mouse:
Press your left mouse button once. You generally click your mouse on something to select something on the screen.
Press your left mouse button twice. Double-clicking something on the computer screen generally opens whatever item you have double-clicked.
Press your right mouse button. When you right-click anything on the computer screen, the program displays a shortcut menu containing commands specific to the selected item.
Move your mouse pointer and hover it over an item on the screen. Press and hold down the left mouse button. Now, move the mouse to where you want to place the item and then release the button. You use this method to move an item from one area of the computer screen to another.
