vimrc

" Mega VIM TIP:
" The following command dumps all Vim mappings to a file.
"
" To find out which plugin created a mapping, you can do a git bisect run until
" you find what's responsible.
"
" vim -s <(echo -e ':redir! >vim-mappings.txt\n:silent map\n:redir END\n:q\n')
"
" the following is also useful
" :verbose map <c-s>
" gives you details about the given mapping ( in our case <c-s>)
