This should get you comfortable with using the h,j,k,l mapping then. I actually turn arrow keys off in my vimrc, I can definitively say it is one of the things that has made me faster.
I use them for buffer switching, since I do that frequently. Left and right change to the next and previous buffers, respectively. Down to quickly swap to the previously focused buffer. Up to bring up a buffer switch menu. Here are the .vimrc lines:
" Arrow keys for buffer switching
nnoremap <left> :bprev<cr>
nnoremap <right> :bnext<cr>
nnoremap <down> :buffer #<cr>
nnoremap <up> :buffers<cr>:buffer<space>
