Hand signals were used by many during the Clone Wars. Jedi Masters Eeth Koth and Obi-Wan Kenobi learned these signals. During a message sent after the Capture of Eeth Koth, Commander CC-3636 "Wolffe" discovered a hidden message sent by Koth. Kenobi was present during the meeting, and was able to identify the signals. This resulted in the Battle of Saleucami and the rescue of Koth.
