(C-a w, C-a C-w)
Uses the message line to display a list of all the windows. Each
window is listed by number with the name of the program running in the
window (or its title).
The current window is marked with a `*';
the previous window is marked with a `-';
all the windows that are logged in are marked with a `$' (see section 10.4 Login);
a background window that has received a bell is marked with a `!';
a background window that is being monitored and has had activity occur is
marked with an `@' (see section 10.6 Monitoring);
a window which has output logging turned on is marked with `(L)';
windows occupied by other users are marked with `&'
or `&&' if the window is shared by other users;
windows in the zombie state are marked with `Z'.
If this list is too long to fit on the terminal's status line only the
portion around the current window is displayed.
