Salesforce Global Variables in classes
Introduction
In this topic I would like to mention all possible global variables which can be used in Apex code. Like [UserInfo Class][1]. I suggest we just list a global classes/variables and links. If you know about a global class/variable but can't find a documentation, please provide as much information as possible.
