In Windows I never turn my NumLock on. I navigate through the page line with Home and End, and when I want to mark a line I use them in a combination with the Shift key. Pretty basic stuff right? Well I don't know how to do it in Ubuntu 10.04. The Home and End keys work but if I hold the Shift key it inputs respectively 7 and 1. If I turn the NumLock on it works but if I am not holding the Shift key it prints 7 and 1 again. Is there any way I can use my keyboard in Ubuntu the same way I do in Windows?
P.S. My roomy is much more experienced than me in Linux so he suggested that xmodmap might work, but even if this is the approach I should take, I still don't want to dig into the whole documentation, just the cliff notes for this exact task if you please.
