On class, method, inner class, property and so on allow to copy full name to clipboard:

namespace MyCompany.MyProduct.Subsystem
{
  class Entity
  {
    void foo|(); // caret here
  }
}

Should put "MyCompany.MyProduct.Subsystem.Entity.foo" string to clipboard.

Rationale: Communicate exact entity to some external resource, like bugtracking system, team members, documentation, etc.

Ideally, accompanying feature like "Goto full name" would be nice, so that pasting such full name would position caret at the entity.
