Opening a window in a horizontal split of a vertical split

Question

I want have both NERDTree and TagList open at the same time, but I don\'t need for them to have the whole height of the screen. Instead I would like to have them split horiz

Answer 1

Horizontal split:

:split 

Vertical split:

:vsplit

Then when you have split your screen how you prefer, open nerdtree inside the desired frame. (Or you can use abbreviation :sp :vsp like suggested by @Vivek Pandey).
