This window contains an IOKit folder, which contains default Tags of the IOKit library that allow reading and writing general or status parameters, for example, and an Offline folder, which contains Tags from agents, according to the modules imported from MIB files.

To use these Tags in an application, drag a Tag or folder from the list on the right (Tags available from driver) to the list on the left (Tags from current project).
