my vim got mad!
 

can anyone tell me how can I correct up the keymaps for my vim cause
when i press up arrow instead of going upwared it writes "A" similarly when pressing down arrow instead of going downward it writes "B".
I don't know why it is showing this behaviour, can anybody please tell me what to do?

less /usr/doc/vim-6.3/doc/vimrc_example.vim
read through that

Try :
cp /usr/share/vim/vim63/vimrc_example.vim ~/.vimrc

Then start vim

how can i set up a color scheme?
cause when i open files in /etc/rc.d
it shows them only in two color grey and white

After copying /usr/share/vim/vim63/vimrc_example.vim in my home dir and rename it .vimrc,

I usually add this line in my ~/.bashrc :

export VISUAL=vim

Also to enable this for root user, I copy the .vimrc in /root and modify /root/.bashrc the same
way
