Totally TAGS list

There are more TAGS than those shown in the dropdown menu.
where can I find a total list of all the tags I can use?

I do not know of any other tags than these described here:

According release notes, in latest beta version 1.3.8 there was added one new tag and some conditions that may be documented later
Add ‘Event’ condition including unread notification and low battery in Conditional line.
Add some conditions for unread notification and locale in Run tab.
Add new Tag expression. (UNREAD_NC)

believes that there have previously been tags for Sun up / down
