Learning the vi Editor, Sixth Edition

9.5. Multiwindow Editing

To create a new window in nvi, you use a capitalized version of one of the ex editing commands: Edit, Fg, Next, Previous, Tag or Visual. (As usual, these commands can be abbreviated.) If your cursor is in the top half of the screen, the new window is created on the bottom half, and vice versa. You then switch to another window with CTRL-W:

<preface id="VI6-CH-0">
<title>Preface </title>

<para>
Text editing is one of the most common uses of any computer system, and
<command>vi</command> is one of the most useful standard text editors
on your system.

This example shows nvi editing two files, ch00.sgm and Makefile. The split screen is the result of typing nvi ch00.sgm followed by :Edit Makefile. The last line of each window acts as the status line, and is where colon commands are executed for that window. The status lines are highlighted in reverse video.

The windowing ex mode commands and what they do are described in Table 9.1.
