Keyboard Shortcuts The CLI has a range of keyboard shortcuts to assist in editing the CLI commands. The following table describes the CLI shortcuts. Keyboard Key Up-arrow key Down-arrow key Ctrl+A Ctrl+E Ctrl+Z / End Backspace key Description Recalls commands from the history buffer, beginning with the most recent command. Repeat the key sequence to recall successively older commands. Returns the most recent commands from the history buffer after recalling commands with the up arrow key. Repeating the key sequence will recall successively more recent commands. Moves the cursor to the beginning of the command line. Moves the cursor to the end of the command line. Returns back to the Privileged EXEC mode from any configuration mode. Deletes one character left to the cursor position. CLI Command Conventions When entering commands there are certain command entry standards that apply to all commands. The following table describes the command conventions. Convention [ ] { } Italic font Ctrl+F4 Screen Display all Description In a command line, square brackets indicate an optional entry. In a command line, curly brackets indicate a selection of compulsory parameters separated by the | character. One option must be selected. For example, flowcontrol {auto|on|off} means that for the flowcontrol command either auto, on or off must be selected. Indicates a parameter. Indicates an individual key on the keyboard. For example, indicates the Enter key. Any combination of keys pressed simultaneously on the keyboard. Indicates system messages and prompts appearing on the console. When a parameter is required to define a range of ports or parameters and all is an option, the default for the command is all when no parameters are defined. For example, the command interface range port-channel has the option of either entering a range of channels, or selecting all. When the command is entered without a parameter, it automatically defaults to all. 32 Using the CLI
