[vim tip] key mappings for conveniently traversing windows and tabs

mappings-for-windows-and-tabs.vim

" These mappings are based on the default key movement scheme of Vim (h, j, k, l)
" For example, when you want to move to the left tab, press Alt + h
" When you want to move to the window underneath, press Shift + Alt + j
" Paste the below code to your Vim settings file ( ~/.vimrc )

" Map Alt(Meta) key combinations
execute "set <M-l>=\el"
execute "set <M-h>=\eh"
execute "set <M-L>=\eL"
execute "set <M-H>=\eH"
execute "set <M-J>=\eJ"
execute "set <M-K>=\eK"

" Move to next tab page
nnoremap <M-l> gt

" Move to previous tab page
nnoremap <M-h> gT

" Move to upper window
nnoremap <M-K> <C-w><C-k>

" Move to lower window
nnoremap <M-J> <C-w><C-j>

" Move to left window
nnoremap <M-H> <C-w><C-h>

" Move to right window
nnoremap <M-L> <C-w><C-l>

I've written a vim plugin called Vim-Jumparound including the code above and other goodies. Consider using it.
