SO, use the TDC Up/Down/Left/Right HOTAS controls as i find that simpler for slewing.
In TGP SOI page, TMS FWD Short to enter a tracking mode (Area first), that will allow you to slew the pod.
TMS FWD changes tracking mode. TMS AFT Short performs a CZ function
TMS Left will change TV/WHOT/BHOT
Hope this helps
