Hello Stefan,
do you mean Code Templates list?
Because Code Hints are collected from code templates, statistics, keywords from syntax schema and auto correction data, and everythig except of code templates are in Code Completion list.
But, if you have selected text and then would use completion shortcut (by default Ctrl+Space), you should see menu with code templates. First come templates that contain %SelectedText% and %SelectedLine% tags and then rest.
Maybe it is a good idea to include also code templates into normal completion list (optionally) but I need to evaluate it.
Also, code templates are only suggested when they typed completely. Then accepting of it, leads to template expanding.
Yellow background indicates, that only one match for typed prefix found, inversed background shows that more then one completion exist.
