Partial Keyword Lookup
If you terminate a partial keyword with a question mark, alternatives that
match the initial letters are provided. (Remember not to leave a space
between the command and question mark.) For example "s?" shows all
the keywords starting with "s."
Console#show s?

Negating the Effect of Commands
For many configuration commands you can enter the prefix keyword "no"
to cancel the effect of a command or reset the configuration to the default
value. For example, the logging command will log system messages to a
host server. To disable logging, specify the no logging command. This
guide describes the negation effect for all applicable commands.
Using Command History
The CLI maintains a history of commands that have been entered. You
can scroll back through the history of commands by pressing the up arrow
key. Any command displayed in the history list can be executed again, or
first modified and then executed.
Using the show history command displays a longer list of recently
executed commands.
Understanding Command Modes
The command set is divided into Exec and Configuration classes. Exec
commands generally display information on system status or clear
statistical counters. Configuration commands, on the other hand, modify
interface parameters or enable certain switching functions. These classes
are further divided into different modes. Available commands depend on
the selected mode. You can always enter a question mark "?" at the prompt
to display a list of the commands available for the current mode.
