Ctrl+W h/j/k/l     change split
Ctrl+W +/-         increase/decrease height (ex. 20<C-w>+)
Ctrl+W >/<         increase/decrease width (ex. 30<C-w><)
Ctrl+W _           set height (ex. 50<C-w>_)
Ctrl+W |           set width (ex. 50<C-w>|)
Ctrl+W =           equalize width and height of all windows
Ctrl + w _ max out the height of the current split
