Each input title is processed in turn. The value of field F in the corresponding tiddler is examined.
- each
- As long as the value of the field is unique (i.e. has not been encountered before), the title is appended to the output.
- each:list-item
- The value is treated as a title list. Each title in the list considered in turn. If it has not been encountered before, it is appended to the output.
- each:value
- As long as the title is unique it is appended to the output whether or not the corresponding tiddler exists.
If a tiddler does not contain field F, it is treated as if the value of the field were empty.
