vi split Screen

Split Screen

Lesson 6 | Lesson 8

To use a vertical split you will need to invoke vim, the updated version. Once the window opens:
:split

or vsplit with some versions.
:vsplit

If you split the screen you can exit the split with:

:q

That will shut down one split at a time.

The CTRL+W CTRL+W command will allow you to move between windows.
