[TxMt] pdfsync problem in multiple input files

[Xuehai Qian]

Hi Everyone,
     I am pretty new in textmate, but I found it is great software and  
I use it everyday now. One problem with me is the pdfsync, I currently  
use skim as the pdf viewer, and from skim, I can find the point in tex  
file by shift+cmd+click, but from tex file I have some problem: my  
paper includes multiple files, I think I can only find the place in  
skim by (control+option+cmd+o) in the master file (which includes the  
titles of different sections), for example, I put the mouse in one of  
the title, and I can be directed to the right place in pdf  
viewer(skim), but if I go to one of the input files, and select a  
place, nothing happens, or it produces the wrong pdf file by the input  
file, and it doesn't make sense.
    Anyone can tell me how to point to a place in tex file (not master  
file but one of the input files) and find the place in pdf file? Thanks!
