Editted: A few changes in order as I think I am seeing things
What I could have added was that my description works when I use pclos2010-KDE and kwrite, that is what gets me. I thought LXDE was close enough to KDE pclos.
I am happy to say the problem is solved after 3 days on and off minor configuring kwrite I finally got it. There is an option to wrap
the cursor, when that is set I get my 'normal way' , ie editing will work just like when using the forum edit box.
If wrap is not set, kwrite will appeal to programmers, or better suited for programming as I understand. I am very happy.
Not an LXDE problem, so this topic landed in the wrong section.
