To delete all aliases in a command mode or a specific alias, enter the no form of the alias command.
In the following example, an alias named "my-cookie" is created for the interface POS 0/1/0/1:
RP/0/RP0/CPU0:router(config)# alias interface my-cookie POS 0/1/0/1
The alias named my-cookie can then be used to identify and configure the interface:
RP/0/RP0/CPU0:router(config)# interface my-cookie
RP/0/RP0/CPU0:router(config-if)#

Keystrokes Used as Command Aliases

The system can be configured to recognize particular keystrokes (key combination or sequence) as
command aliases. In other words, a keystroke can be set as a shortcut for executing a command. To
enable the system to interpret a keystroke as a command, use the Ctrl-V or Esc, Q key combinations
before entering the command sequence.
