Fujara fingerings:

Scatter. A high-intensity ornament particular to the fujara that is often used at the beginning of songs. It begins with a high-itensity, repeated percussive blow that can be made by saying something like "DA DA DA Da Da Da da da da ..." Where the pressure of each "Da" gets less and less and the fujara descends through the overtone scale.
Woosh. An ornament added onto the end of some notes in a song. It is done with a steady, rapidly increasing blow of air that cause a very fast ascending scale up the fujara.

Wiggly Line: That symbol in the finger diagrams is intended to convey a trill on that hole. The hole for the trill is typically one that causes a small change in pitch (maybe a 1/4 tone) so the effect is a vibrato. This seems to me to sound better than trying to do vibrato from the diaphram.
