[Dx4win] FSK in Version 7

[Bud Governale]

The DX4WIN version 7 manual refers to AFSK keying. Is FSK keying possible?
I have MMTTY set up and working using FSK keying.
I also have MMTTY integrated with N1MM using FSK keying.
Is it only necessary to setup the RTTY PTT com port in DX4WIN?
Using DX4WIN, will FSK keying be sent to the TXD line since MMTTY is setup for FSK keying or is this an item that needs 
to be selected in DX4WIN? If so, where?
