Reformat, please, using <code>...</code> tags around your code -- See Markup in the Monastery -- or, at least, pay heed to the instructions above and below the text entry box.

Edit; don't create a second node when you screw up the first.

Please state your problem clearly -- in this case, you might have asked (naively) "what values are returned by the arrow keys?" But if that's your intent, that's not a Perl question; it's one you might better answer for yourself by using Google or the like. And since you don't tell us the values to which you applied \x and \0, nor precisely how, any reply is likely to be no better than a WAG.

I hope (but am not certain) that this hint may be helpful: "keycodes" and/or "scancodes"
