User’ Guide 33
To list keywords or arguments, enter a question mark (?) in place of a keyword or argument. Include a space
before the ?. This form of help is called command syntax help, because it reminds you which keywords or
arguments are applicable based on the command, keywords, and arguments you already have entered. This
example shows what the show ? command displays on an Ambit Cable router:
