Open NERD_Tree to your project folder, by typing :NERDtree /path/to/project or by using bookmarks. Place the cursor on a folder and type the letter m.

If your search will yield results, you will see a window in the lower part of your screen, with all the results. Navigate with the keys and press <CR> to jump to a result. The file will be opened in the last working window.
