Note: Some keyboard shortcuts perform different functions based on cursor location (focus). If there is more then one plus sign (such as Ctrl+Shift+C), it means that all three buttons surrounding the plus sign must be pressed at the same time. Tip: The plus sign (+) means that you must press two keys surrounding the plus sign at the same time. For example, to copy in Windows, press Ctrl and C at the same time. To perform a command, press the buttons listed together at the same time.
