always|splitonly [string]string [string](none)
This command controls the display of the window captions. Normally
a caption is only used if more than one window is shown on the
display (split screen mode). But if the type is set to
always, screen shows a caption
even if only one window is displayed. The default
is ‘splitonly’.
The second form changes the text used for the caption. You can use
all string escapes (see String Escapes). Screen uses
a default of ‘%3n %t’.
You can mix both forms by providing the string as an additional argument.
