A Vim Must-Have: NERDTree →
This is an absolute must if you’re using Vim full time. It’s especially helpful on new projects where you’re not entirely familiar with the file structure. Once you’ve got it installed this is a great hack to drop in your .vimrc file to help you both mirror and toggle the file list with a single keystroke:
" guarantees that the NERDTrees for all tabs will be one and the same
map <F2> :NERDTreeToggle \| :silent NERDTreeMirror
A special thanks to Guilherme De Napoli for the shortcut mapping.
