Pg 55 of the manual

CW WGHT 1.15 Adjusts element/space timing ratio (weight) for the 
internal keyer.
Additional functions of this menu entry, via numeric keypad (Advanced):
Tap 1 to select SSB -CW (default) or SSB +CW (allows CW in SSB modes).
Tap 2 to select @ = STOP (‘@’ character terminates KY-packet transmission;
default) or @ = ‘AC’ (‘@’ in a KY packet is sent as .--.-. [@] in CW mode).
Tap 3 to select OLD or NEW QSK (default). NEW reduces AF keying artifacts.
Tap 4 to select VOX NOR (default) or AUTO OFF. The AUTO OFF setting
turns CW VOX off on power-up, avoiding accidental keying by attached 
PCs, etc.
Tap 5 to select automatic VFO offset on SSB/CW mode change (VFO OFS) or
no offset (VFO NOR, default). Automatic offset is often used on 6 
meters, where
mixed-mode QSOs are necessary during fading. Note: Pitch matching will be
more accurate if USB is paired with CW REV, and LSB with CW normal.

Tap 1 if you want to send cw while in ssb mode.
