[TEC] Syntax Help, Please

[torpedobait]

After doing a complete uninstall and then a new reinstall to v1.5, I switched from TMO 2.5 with RSRD to GFO with RSRD just for the sake of variety. One thing I didn't like in GFO was that the W key cycled through all torpedo tubes, whereas in TMO it only cycled the forward tubes, and the E key cycled the stern tubes. Being a clever old programmer from WAAAAAY back, I thought I'd just add the Stern tube command to the data/cfg/commands file. Nothing is that simple. All of the varieties other than TMO use the E key for Emergency Surface. I'd like to change the Emergency Surface command in GFO to require CTL+S, but this syntax is apparently not correct:

[Cmd202]
Name=Emergency_surface
Ctxt=1
MnID=0x3F230003
Str=1034
Key0=0x45,C,"CTRL S"

I've also tried Key0=0x45, Cc="CTRL S" to no avail.

Can anyone put me on the right path so I can make this "simple" change? it's driving me nuts. Thanks in advance!
