Chapter 5 CLI Tips, Techniques, and Shortcuts

Key Combinations

Recalling Deleted Entries

The Cisco IOS XR CLI also stores deleted commands or keywords in a history buffer. The buffer stores
the last ten items that have been deleted using Ctrl-K, Ctrl-U, or Ctrl-X. Individual characters deleted
using Backspace or Ctrl-D are not stored.

Table 5-7

identifies the keystroke combinations used to recall deleted entries to the command line.

Note

The Esc, Y key sequence does not function unless the Ctrl-Y key combination is pressed first. If the
Esc, Y is pressed more than ten times, the history cycles back to the most recent entry in the buffer.

Redisplaying the Command Line

If the system sends a message to the screen while a command is being entered, the current command line
entry can be redisplayed using the Ctrl-L or Ctrl-R key combination.
