only difference between this and \{{$*pagename*#*fieldname*}} is
that the full name of *pagename* is calculated relative to the

### Escaping
Getfield markup can be escaped by putting a backwards slash `\`
in front of the markup.
If that is done, then the markup is displayed as-is.
### No Value Found
If no value is found for the given field, then the field name is returned.
