sometimes, vim can seem stupid, like when in insert mode, the arrow keys and the backspace key actually type characters, rather than moving the cursor around. you find yourself having to constantly switch between insert and view mode… this is lame

thankfully, vim can be customised to behave more intuitively, by way of a config file called .vimrc (or .virc, if you use vi), which goes in your user’s home directory. you can create one

$ vim ~/.vimrc

here’s a really great example vim configuration i came across at http://amix.dk/vim/vimrc.html
