The Cisco IOS software user interface provides a history, or record, o
commands that you have entered. This feature is particularly useful fo
recalling long or complex commands or entries, including access lists.
By default, the system records 10 command lines in its history buffer.
The following commands are entered from user EXEC mode.
Warning: Many of the commands described in this section refer to
arrow keys as well as alternate keystrokes. Please note
that arrow keys function only on ANSI-compatible termi
nals such as VT100s.
