A +ListTextField maps text to a list of strings. Normally used as a
    single line text field and takes a list of delimiters as argument:
    
    (gui '(+SetEAdr +E/R +ListTextField) '(to : home obj) '(", " "," " ") 60)
    
    The example above creates a text field connected to the 'to' property of the
    current object. Entering e-mail addresses in this field, separated by a
    comma followed by a space, just a comma or just a space will map the
    addresses to a list: "foo@domain.com, bar@domain.com baz@domain.com" -->
    ("foo@domain.com" "bar@domain.com" "baz@domain.com") See also gui, +TextField
    and input fields.
