Hi. Sorry this message slipped through my focus until now. :-)

In general I do like the idea. The only problem is that exactly this same 
mechanism is already now used to switch from simple "automatic" completion 
mode into full "user-invoked" completion mode within kdevelop.

This means that when there is a simple completion, and the user presses 
CTRL+Space, he sees more.

Now one could of course implement that when he presses _again_, the next item 
in the list is selected. That should be pretty easy to implement within 
katecompletionwidget.cpp and kateviewinternal.cpp.

It should then probably be like this: When the current completion is not yet 
an user-invoked completion, do the same thing we do now.
When it already is a user-invoked completion, move to the next item instead of 
starting it again.

Greetings, David
