User’s Guide 31
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:
CM>show ?
dhcp Display all options in DHCP response

downstream Display current downstream information
upstream Display current upstream information

cpe-limit Display CPE limit information

To complete a partial command, keyword, or argument use the <Tab > key. This example shows
what how <Tab> key works:
CM>show inter<Tab>
CM>show interface
