Similarly, you can press the Down Arrow, Right Arrow, Left Arrow, and Delete keys to navigate through the command history and to modify an existing command string. Getting Help In any command mode, you can get a list of available commands by entering a question mark (?). switch# ? To obtain a list of commands that begin with a particular character sequence, type in those characters followed immediately by the question mark (?). Do not include a space. switch# co? configure copy To list keywords or arguments, enter a question mark in place of a keyword or argument. Include a space before the question mark. This form of help is called command syntax help, because it reminds you which keywords or arguments are applicable based on the commands, keywords, and arguments you have already entered. switch# config ? terminal Configure the system from the terminal Tip If you are having trouble entering a command, check the system prompt and enter the question mark (?) for a list of available commands.
