Question

When using NERDTree, I would like to remap the left and right arrow to move up and down a directory.

I believe the left arrow has to be mapped to 'u' but I do not know how to do this only when NERDTree is the active window.

Thanks!

Was it helpful?

Solution

Try this:

autocmd FileType nerdtree nmap <buffer> <left> u
