The Properties editor shows and allows editing of many active data, including the active scene and object.
The Properties editor has several categories, which can be chosen via tabs (the icons column to its left). Each tab regroups properties and settings of a data type, and is documented in its own manual sections, linked below.
Active Tool and Workspace settings¶
These tabs contain settings for the active scene.
These tabs are used to add features, and to change properties for the active object. Depending on the type of the active object, some of those will be hidden.
The main tab of that category (often the only one) always has the same name, Object Data, but its icon will change based of the actual type of the active object.
In the header of this editor, a list of icons and text items shows the owner of the the properties being edited, together with some dependency context if needed. In the example above, the material Material is used by the active object Cube.
By toggling on the pin symbol to the ride, Blender can be told to display in that editor only the currently shown data-block's properties, disregarding further selection changes. Toggle off that pin to switch back to default behavior, showing active data-block's properties.
