Then you should start learning how to use Vim, properly ;).

Start from the basics, work your way up. From your post it is painfully obvious that you don't really use Vim to it's fullest potential. Vim requires a completely different way of thinking than regular text editors, and, it requires time to learn.

Only use up down with kj for fine movements. Large movements happen with gg, G, preset marks, and <C-d> and <C-u> which are half screens down and up for me respectively. That covers vertical movement. Most of my horizontal movement is done with either f or vim-seek (which is like f but takes 2 characters!)
