It's worth to write about your learning's. Even if they seem small.
Recently I turned of my arrow keys in VIM and blogged about it.
After reading my article Philipp Fehre suggested, that I could take this a step further and use the arrow keys for resizing panes.
So I went ahead and copied the following 5 lines from his .vimrc:
" Make arrowkey do something usefull, resize the viewports accordingly nnoremap <Left> :vertical resize +5<CR> nnoremap <Right> :vertical resize -5<CR> nnoremap <Up> :resize +5<CR> nnoremap <Down> :resize -5<CR>
Phil was right! This is a great way of resizing panes.
