escape-key { default | character }

User interface view

character: Specifies the shortcut key for aborting a task, a single character (or its 
corresponding ASCII code value in the range 0 to 127) or a string of 1 to 3 
characters.

default: Restores the default escape key combination <Ctrl+C>.

Use the escape-key command to define a shortcut key for aborting tasks.

Use the undo escape-key command to disable the shortcut key for aborting 
tasks.

You can use a single character (or its corresponding ASCII code value in the range 
0 to 127) or a string of 1 to 3 characters to define a shortcut key. But in fact, only 
the first character functions as the shortcut key. For example, if you enter an ASCII 
code value 113, the system will use its corresponding character q as the shortcut 
key; if you input the string q@c, the system will use the first letter q as the shortcut 
key.

By default, you can use <Ctrl+C> to terminate a task. After defining a new 
shortcut key using the escape-key command, the new shortcut key will take the 
place of <Ctrl+C> to abort the task. You can use the display 
current-configuration command to display the shortcut key you have defined.

# Define <a> as the escape key.

To verify the configuration, do the following:

# Use the ping command to check the reachability of the device with the IP 
address of 192.168.1.49 and use the -c argument to specify the number of the 
ICMP echo packets to be sent as 20.
