[OS X TeX] How to get rid of BibDesk Service shortcuts?

[Joachim Kock]

Hello,

BibDesk installs two Services with global shortcuts 
Cmd-shift-J and Cmd-shift-K.  

These shortcuts override application-specific shortcuts
I rely on in other applications.  It is really annoying.

Is there a way to get rid of the BibDesk shortcuts?

Thanks a lot in advance.

Joachim.
