The trouble here is that those codes are *very likely* likely to have
changed between V3 and V4 since there was a large rewrite between the
two. That's why looking at the source code is necessary to get you the
help you need.

Which is why you need to look at the source code. Documentation isn't
always clear or definitive but the source code will tell you.

Mostly it is, but there are always mysteries like this.
