Hostname#help
Help may be requested at any point in a command by entering
a question mark '?'. If nothing matches, the help list will
be empty and you must backup until entering a '?' shows the
available options.
Two styles of help for command are provided:
1. Full help is available when you are ready to enter a
command argument (e.g. 'show ?') and describes each possible
argument.
2. Partial help is provided when an abbreviated argument is entered
and you want to know what arguments match the input
(e.g. 'show pr?'.)
And "Edit key" usage is the following:
CTRL+A -- go to home of current line
CTRL+E -- go to end of current line
CTRL+U -- erase all character from home to current cursor
CTRL+K -- erase all character from current cursor to end
