Tab Completion
By entering the first letter of a command at any menu prompt and pressing the Tab key, the CLI displays all commands or options in that menu that begin with that letter. Entering additional letters further refines the list of commands or options displayed. If only one command fits the input text when Tab is pressed, that command displays on the command line, waiting to be entered. If you press the Tab key without any input on the command line, the currently active menu displays.
