This document uses the following format for listing shortcuts:
Example:
| Command | Windows | Mac | Linux | 
| Copy | Ctrl+C | Cmd+C | Ctrl+C | 
To perform a command, press the buttons listed together at the same time. For example, to copy in Windows, press Ctrl and C at the same time.
Tip: The plus sign (+) means that you must press two keys surrounding the plus sign at the same time. 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.
Abbreviations:
Note: Some keyboard shortcuts perform different functions based on cursor location (focus). For example, if you press Home on Windows while viewing a web page, Mozilla will move to the top of the web page. However, if you press Home on Windows while the cursor is in a text field, the cursor will go to the beginning of the text field.
