When on, the title of the window will be set to the value of 'titlestring' (if it is not empty), or to: filename [+=-] (path) - VIM Where: filename the name of the file being edited - indicates the file cannot be modified, 'ma' off + indicates the file was modified = indicates the file is read-only =+ indicates the file is read-only and modified (path) is the path of the file being edited - VIM the server name v:servername or "VIM" Only works if the terminal supports setting window titles (currently Amiga console, Win32 console, all GUI versions and terminals with a non-empty 't_ts' option - these are Unix xterm and iris-ansi by default, where 't_ts' is taken from the builtin termcap).

When Vim was compiled with HAVE_X11 defined, the original title will be restored if possible. The output of ":version" will include "+X11" when HAVE_X11 was defined, otherwise it will be "-X11". This also works for the icon name 'icon'. But: When Vim was started with the -X argument, restoring the title will not work (except in the GUI). If the title cannot be restored, it is set to the value of 'titleold'. You might want to restore the title outside of Vim then. When using an xterm from a remote machine you can use this command: rsh machine_name xterm -display $DISPLAY & then the WINDOWID environment variable should be inherited and the title of the window should change back to what it should be after exiting Vim.

(default off, on when title can be restored)
