Deleting all lines containing a pattern seems not to be implemented:
:g/MyPattern/d
after hitting this in Vi Mode, it says: ":g is not an editor command"
This should be implemented, it belongs to the most imporant features of Vi like stuff.
It is basic functionality.
Tested only on specified QtCreator version, but i guess it applies to all versions.
