TSref is a great help when working with TypoScript. The original document is available at http://typo3.org/documentation/document-library/references/doc_core_tsref/current/view/.
There is also a reference at the end of this book listing relevant objects and properties. The broad topics covered by TSref are outlined in the following sections.
The first section introduces the datatypes that are used in TypoScript. There is an example and a default value for each one.
This chapter demonstrates how to use objects and their properties. Besides referencing the usable datatypes, there is also a comprehensive explanation of optionSplit. OptionSplit
allows you to assign different values to objects in an array with only one value assignment.
