Its my understanding we're not using this, can it be removed now?

[Jered, 2012/07/19 22:01:33]

It's still referenced several places in the code, so naively, I don't think so.

I think it can be removed from all of them. But, that can be done later.

I will wait, then.

   INSTANT_COMPLETE_DELAYED,
 
-  // Never complete the suggestion.
+  // Do not autocomplete the suggestion. The suggestion may still be displayed
+  // in the omnibox, but not made a part of the omnibox text by default (e.g.,
+  // by displaying the suggestion as non-highlighted, non-selected gray text).
