@ -23,7 +23,7 @@ The parameter <<.place C>> is one of the following fundamental categories:
|^`tag` |is in use as a tag |
|^`tiddler` |exists as a non-shadow tiddler |
If <<.place C>> is anything else, the output is an error message.
If <<.place C>> is anything else an error message is returned. <<.from-version "5.1.14"> if <<.place C>> is blank, the output is passed through unchanged (in earlier versions an error message was returned).
`!is[tiddler]` is a synonym for `is[missing]`, and vice versa.
