Basic Properties
When tags are created, they are automatically given a name according to their function. For example, a Vertex Map tag is appropriately called a "Vertex Map".
However, you can also give all objects and elements (e.g. shaders) any name you like. The object or element appears under this name, e.g. in the XPresso Editor or in the Timeline or link fields.
So far, so good. However, there are tags that can be assigned as often as required (e.g. Selection tags, Vertex Color tags, etc.). If they all had identical names, this could lead to problems. Imagine 2 Polygon Selection tags with the same name and you want to restrict a material to one of the selections: this becomes difficult with identical names, as only the Selection tag furthest to the left is used.
This is why Cinema 4D numbers them consecutively where it makes sense. For example, 3 Polygon Selection tags on the same object:
- Polygon Selection
- Polygon Selection.1
- Polygon Selection.2
This automatic numbering occurs when creating tags using the menu/command, when duplicating with the ctrl key and with some tag-creating tools such as the Paint Tool, MoGraph Selection, Bind Tool, etc.
If the element (object, tag, track, etc.) has been assigned to a layer, you will find the layer name and color here. Layers can be dragged here directly from the Layer Bowser or from other similar fields. You can also use the menu behind the small triangle button on the right to assign layers or remove the element from the current layer. Show in Manager opens the Layer Manager.
Click on the small triangle to the left of Layer to show the layer properties. This gives you access to all properties that are otherwise only accessible via the Layer Manager.
Use this setting to turn animation tracks off, i.e., the track will not be animated despite existing animation. This state will automatically be inherited by the Child objects (Child objects’ states can nevertheless be switched independently of the Parent objects). The same functionality can be found in the layer column in the form of an Film Strip icon that can be turned on or off.
Activate this setting if you want to switch the track to Solo Animation mode, i.e., only that track will be animated and all others will be turned off. This state will be inherited by all Child objects but can be changed on an individual basis. The same functionality can be found in the layer column in the form of a film strip that can be turned on or off.
If this option is enabled the colors defined in the Preferences menu ( track X/Y/Z color) for the F-Curves will be used in both 
Dope Sheet and 
F-Curve Mode. If this option is disabled, the color can be defined freely (for most Tracks).
