You can type Esc+. (period) or Alt+. (period) to insert the last word of the previous command. Repeat Esc+. or Alt+. to scroll backwards through the list of —testrecently entered words. For example:
user@host> show interfaces terse fe-0/0/0
Interface Admin Link Proto Local Remote fe-0/0/0 up up fe-0/0/0.0 up up inet 192.168.220.1/30
user@host> <Esc>
user@host> fe-0/0/0
If you scroll completely to the beginning of the list, typing Esc+. or Alt+. again restarts scrolling from the last word entered.
