Text
Renders the field exactly how it is stored.For example
<<view modified text>> <<view title text>>gives:
Link
Renders the value of the field as a link<<view title link>>gives
Date
Applicable to the modified and created fields. Note a further parameter - a date format can be used.<<view created date>> <<view modified date "YYYY">>gives:
Wikified
Treats the string as wikitext.e.g.
<<view customfield wikified>>
An optional third parameter can be used to transform the text before it is wikified. For example:
<<view customfield wikified "//%0//">>
The result of this example would be to make the field display in italics.
(Notice: the placeholder starts with a '%', in contrast to the placeholders used by the tiddler macro that start with '$')
