Overview

Postfix code completion lets you transform an already typed expression to another one based on the postfix you type after a dot, the type of the expression, and its context. This transformation is performed by expanding the postfix-specific predefined template. For example, the .if postfix applied to a boolean expression wraps it with an if statement. See more at: Postfix Code Completion.

On this page, enable and disable postfix templates and appoint key to activate the template expansion.
