Key Function
Common keys
If the edit buffer is not full, pressing a common key inserts the character at the

Deletes the character to the left of the cursor and moves the cursor back one
character.
Left arrow key or

The cursor moves one character space to the left.
Right arrow key or
Ctrl+F

Tab
If you press
Tab
after entering part of a keyword, the system automatically
completes the keyword:
•
If finding a unique match, the system substitutes the complete keyword for
the incomplete one and displays it in the next line.
•
If there is more than one match, you can press
Tab
repeatedly to display
in cycles all the keywords starting with the character string that you typed.
•
If there is no match, the system does not modify the incomplete keyword
and displays it again in the next line.
Typing incomplete keywords
You can input a command comprising incomplete keywords that uniquely identify the complete
command.
In user view, for example, command
system-view
, to enter system view, type
sy
.
You can also press
Tab
to have an incomplete keyword automatically completed.
Configuring command aliases
The command keyword alias function allows you to replace the first keyword of a non-undo command or
the second keyword of an
undo
command with your preferred keyword when you execute the command.
For example, if you configure
show
as the alias for the
display
keyword, you can enter either
show clock
or
display clock
to execute the
display clock
command.
Usage guidelines
•
After you successfully execute a command by using a keyword alias, the system displays and saves
the keyword, instead of its alias.
•
When you define a command alias, the
cmdkey
and
alias
arguments must be in their complete
form.
