writing mouting of words with SSW

[eghoffma at UMICH.EDU]

Hi - In the video I'm transcribing of Nepali Sign Language, words are 
occasionally mouthed along with the signs. I see that there are a 
variety of mouthshapes available in the Sign Text Editor - do I choose 
the mouth shape that most closely approximates the shape the signer's 
mouth takes as they mouth the word? Or is there a symbol to indicate 
more generally that the sign is accompanied by a mouthed word?
Thanks!
