You can customize each window's name in the window display (viewed with
windows command (see Windows) by setting it with
one of the title commands. Normally the name displayed is the actual
command name of the program created in the window. However, it is
sometimes useful to distinguish various programs of the same name or to
change the name on-the-fly to reflect the current state of the window.
The default name for all shell windows can be set with the
shelltitle command (see Shell). You can specify the name you
want for a window with the ‘-t’ option to the
when the window is created (see Screen Command). To change the name after
the window has been created you can use the title-string escape-sequence
(<ESC> k name <ESC> \) and the
(C-a A). The former can be output from an application to control the
window's name under software control, and the latter will prompt for a
name when typed. You can also bind predefined names to keys with the
title command to set things quickly without prompting.
