[squeak-dev] problem with OCompletion

Ok, thanks.  But I'm wondering; how do I access OCompletion?

Here is how I installed it:

   trunk image
   loaded RoelTyper-FredericPluquet.82
   loaded Ocompletion-ul.88

Then:

    - Opened a hierarchy browser on one of my classes
    - Select a method, select all text, begin a new method, "test"
    - The class has an api of three messages that begin with the word "add"
    - In the body of the method, I type "self ad" but nothing appears.
    - I tried typing Tab, Alt+Space, Control+Space

So I decided to study accessors of ECPreferences class>>#enabled.

There do not seem to be any!  Browse refererences to ECPreferences,
then filter by messages that send #enabled..

How is OCompletion functionality invoked?
