Map F2 to NEERDTreeToggle

Question

I want just to open and close NERDTree, pushing the F2 button. I've mapped it in this way :

map <silent>  <F2> NERDTreeToggle 

But, Actually this doesn't work properly and I haven't understood why...

Answer 1

Here is my config for NERDTree.

silent! nmap <C-p> :NERDTreeToggle<CR>
silent! map <F3> :NERDTreeFind<CR>

let g:NERDTreeMapActivateNode="<F3>"
let g:NERDTreeMapPreview="<F4>"

F3 will open NERDTree panel and highlight current file. And when you're in the NERDTree panel, F3 will open file under cursor. So, I can use one button to jump between buffer and NERDTree. (And F4 for preview because it's next to F3)

Answer 2

your mapping:

map <silent> <F2> NERDTreeToggle

should be:

map <F2> :NERDTreeToggle<CR>

I think you'll find that'll work (you basically missed the colon and the <CR> to make the action happen...
