•Wildcards, Templates, and Aliases, page 5-11

•Command History, page 5-17

•Key Combinations, page 5-18

Note Commands can be entered in uppercase, lowercase, or mixed case. Only passwords are case sensitive. However, the Cisco Systems documentation convention presents commands in lowercase.

The following sections describe tips and shortcuts useful when using the CLI:

•Entering Abbreviated Commands, page 5-1

•Using the Question Mark (?) to Display On-Screen Command Help, page 5-2

•Completing a Partial Command with the Tab Key, page 5-4

•Identifying Command Syntax Errors, page 5-4

•Using the no Form of a Command, page 5-4

•Editing Command Lines that Wrap, page 5-5

Entering Abbreviated Commands

You can abbreviate commands and keywords to the number of characters that allow a unique abbreviation. For example, the configure command can be abbreviated as config because the abbreviated form of the command is unique. The router accepts and executes the abbreviated command.
