punctuation question

[eghoffma at UMICH.EDU]

Hi -
I was looking over the available punctuation and was wondering - is 
there any way to show that the pause between the end of one sentence 
and the beginning of the next is shorter than is normal? The utterance 
in question has the signer jumping back in very quickly after ending a 
statement to clarify something he'd just said. I guess a written 
English equivalent might be a dash? If there's no SW symbol I can make 
note of it in some other way, but I thought I'd ask.
Thanks,
Erika
