[j-nsp] Arrow keys

[Luis Eduardo Díaz Zazo]

While entering a juniper router by the console port and using the root user,
I am able use the arrow keys to repeat the last command. But if I use the
console port with any of the other users - no matter the level of access
they have - or I use the telnet, I can't use the arrow keys.

Any idea why this happens, and how I can have the arrow keys always working?
