Reference - Macro methods

Macro expressions allow you to use a large variety of methods. The following categories list the methods according to the type of provided functionality:

Keep in mind that the recommended macro syntax is to use infix notation for the first parameter of methods.

For example: {% "word".ToUpper() %} instead of {% ToUpper("word") %}
