as for seeing what has scrolled beyond "weiw" hold shift and use "pg up" and "pg down" keys. usually only works for 100 lines or so, depending on settings.

another thing is that the file /root/.bash_history has all the comands issued by root in a console on that computer, and /home/knoppix/.bash_history has for knoppix user...
Sadly in knoppix that means, for that session, as everything in /root is lost at reboot.
if you have a permanent home knoppix .bash_history is saved though.
please note that the " . " means it is a hidden file, it is not a typo from my part, it is "dot"bash_history.

you can also list several options after the iwconfig. like
Code:
iwconfig eth1 essid "whatever" mode managed key s:whateverkeyis rate auto
as for copy and paste just mark what you wanted copied, go where you want it pasted (without accidentally marking any new text) and and use either the middle button (mouseweel on some) or both right and left simultaniously, now you have the marked text where you had the blinking pionter (say on one of these text feilds).
