Use of Term lists in search - Issues Mac OS 10.6 and EndNote X3

Hello all, 

just a quick question if anyone has the same issues with term lists as I have:

I want to use term lists in my search, e.g. the keywords term lists. So I follow the instructions in the manual (p. 284) but unfortunately upon a double-click the term is not automatically inserted into the search field. Command+1 does also not work as described.

It works when I enter a new reference, but it will not work in searches. 

Does anybody have the same experience?
