(⌘=) shortcut to OmniDictionary, not from OW?

[John Stalberg]

The shortcut in the Services menu for OmniDictionary  (⌘=) doesn´t work 
in OW 5.1 (v563.34) for me. I have tested in TextEdit,  as suggested in 
OmniDictionarys help, with positive result (OD launches as expected). 
In OW (⌘=) seems to be equivalent to (⌘+) wich is calls Bigger Text in 
the View menu. Is this as supposed? If not - any suggestions?
