The other option that can be selected is "word wrap on keyboard"  That option keeps the letter of a word together when you get to the end of a line. However, this is only on the computer screen of the transmitting station as the size of the MMTTY window will vary depending on how the individual operator has set up his MMTTY window. Neither is a big help for a mechanical RTTY machine operator.
