Tag¶

Tag binding is to bind a property directly to a tag property, usually the tag value, but also other properties of the tag. Each time a property of the selected tag changes, the new value is pushed to the bound property. If you select a tag rather than a specific property of that tag, then it is considered to bind to the 'value' property of the tag.
