If it has a window on the screen, it is a buffer;
if it is not on the screen, it is not a buffer.

Hidden A file is being edited, but does not appear onscreen.
Inactive The file is not being edited, but keep the information about it anyway.

• :buffers can also be written as :ls, :files

The CTRL-Wgf command opens a new tab and starts to edit the file who's
name is under the cursor. Vim will search for the file using the same algorithm
as it uses for the :find command. The CTRL-WgF command does the same thing,
only it goes a step farther. It not only starts editing the file in a new tab, but
jumps to the line number following the file name.

• :tabfind
