Within the Doc Center (doc.4d.com) each page within the Language Reference contains a Properties section on the right hand side. For the command pages, the Properties section may contain one or more images, which are links. These image links are provided to help identify commands with similar properties.

Each image corresponds to a specific group and clicking on the image link will display a page with all the commands within that group.

Here are the groups that are currently available:

Group	Description
Current record	Commands that change the currrent record
Current selection	Commands that change the current selection
