## How can I open NERDTree automatically when vim starts up on opening a directory?
autocmd StdinReadPre * let s:std_in=1
autocmd VimEnter * if argc() == 1 && isdirectory(argv()[0]) && !exists("s:std_in") | exe 'NERDTree' argv()[0] | wincmd p | ene | endif
This window is tab-specific, meaning it's used by all windows in the tab. This trick also prevents NERDTree from hiding when first selecting a file.

autocmd StdinReadPre * let s:std_in=1
autocmd VimEnter * if argc() == 1 && isdirectory(argv()[0]) && !exists("s:std_in") | wincmd p | ene | exe 'NERDTree' argv()[0] | endif
The difference between the two is: The first example places the cursor in the empty buffer, while the second example puts it in the NERDTree. This window is tab-specific, meaning it's used by all windows in the tab. This trick also prevents NERDTree from hiding when first selecting a file.
## How can I map a specific key or shortcut to open NERDTree?
Stick this in your vimrc to open NERDTree with `Ctrl+n` (you can set whatever key you want):
map <C-n> :NERDTreeToggle<CR>
