The easiest way to open a new window is to use the following command: >

:split

This command splits the screen into two windows and leaves the cursor in the
top one:

	+----------------------------------+
	|/* file one.c */		   |
	|~				   |
	|~				   |
	|one.c=============================|
	|/* file one.c */		   |
	|~				   |
	|one.c=============================|
	|				   |
	+----------------------------------+

What you see here is two windows on the same file. The line with "====" is
that status line. It displays information about the window above it. (in
practice the status line will be in reverse video.)
The two windows allow you to view two parts of the same file. For example,
you could make the top window show the variable declarations of a program, and
the bottom one the code that uses these variables.

The CTRL-W w command can be used to jump between the windows. If you are in
the top window, CTRL-W w jumps to the window below it. If you are in the
bottom window it will jump to the first window. (CTRL-W CTRL-W does the same
thing, in case you let go of the CTRL key a bit later).
