I'm a Colemak keyboard layout user and I recently started to learn and use Vim.
I was able to map the arrow keys in the normal mode by putting custom mappings such as noremap u k in .vimrc (because the keys h, j, k, and i are in different places in the Colemak layout).
However, when I tried to use NERDTree, navigating through the NERDTree menu became very hard for me for I have to reach j and k key to navigate up and down (those keys are y and k in QWERTY).
Is there a way to map those two keys into other keys?
I would really appreciate any help!
