	Table 5-6	Command History

	Command or Key Combination		Purpose

	Ctrl-P or the up arrow key		Recalls commands in the history buffer, beginning with the most
			recent command. Repeat the key sequence to recall successively
			older commands.

	Ctrl-N or the down arrow key		Returns to more recent commands in the history buffer after
			recalling commands with Ctrl-P or the up arrow key. Repeat the key
			sequence to recall successively more recent commands.

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 5-7identifies the keystroke combinations used to recall deleted entries to the command line.

Table 5-7 Keystroke Combinations to Recall Deleted Entries

Command or Key Combination	Recalls

Ctrl-Y	The most recent entry in the buffer (press the keys simultaneously).

Esc, Y	The previous entry in the history buffer (press the keys
	sequentially).

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.
