I'm having a hard time removing the "Lookup in Dictionary" context menu element in Chrome for Mac (see screenshot).

Chrome's context menu

I tried deactivating the Dictionary Service shortcut in Preferences / Keyboard, and I also tweaked's Info.plist to remove the service. I even removed the entire Dictionary app, but the context menu item still shows. Might it be hard coded into Chrome?

What you are seeing are the OSX built in Text Services, such as Spelling and auto-correct services when dealing with anything in OSX that is text.

These services are automatic for the whole OS and cannot be turned off and are available in every application

Note: Spelling Auto-Correct can be turned off/managed in System Preferences -> Languages & Text -> Text

The "Services Manager" and the "Dictionary Service" only relate to what is shown and provided in the Services Menu within running applications. you can turn off those within (oddly enough) System Preferences -> Keyboard -> Keyboard Shortcuts -> Services

Well, they don't show up in Firefox, for example... as in lots of other apps. And I don't think spelling auto-correct has any impact on this. – julien_c Jan 20 '12 at 11:32
Firefox has it turned off, the context menus are specific to Firefox not OSX. Obviously the Chrome developers are using NSTextView and Firefox is not. – Stu Wilson Jan 20 '12 at 12:21
So I guess I'm stuck with those context menu items no matter what I do then? Unless I fork Chromium and stop using NSTextView? – julien_c Jan 20 '12 at 14:08
that is my belief, yes. – Stu Wilson Jan 20 '12 at 15:02
It's probably not worth it then. Thx! – julien_c Jan 20 '12 at 22:18
