None of the swisentity forms are used outside of alerts, the easy way to see a list of all node properties that you would be able to resolve is to go to a summary resource such as the all nodes, or top volumes/interfaces and click edit and scroll down near the bottom the list of filter examples is actually all of the ones you could use. Just use them like ${caption}, the swis entity stuff basically says "for the object(s) that triggered this alert" but don't apply anywhere else in the UI.
