Thanks, Mario! These are the kinds of tutorials / explanations I'm trying
to build for {{DesignWrite}}. So, at the risk of belaboring the point --
and with apologies to those for whom this it too fine-grained. I've
numbered your three code snippets below (1) (2) (3), added (4). and
I see that in edit mode, (1) and (2) and (4) produce no output, given
that {{!!title}} and <<currentTiddler>> have both taken the value of *Draft
of 'test'*, while in view mode (1) (2) (3) and (4) produce identical
output.
This yields three questions for me:
<A> What are the differences between using a specified transcluded field
in a filter, as in (1), and using a macro <<currentTiddler>> in a filter as
in (2)? In what circumstances is (1) preferred over (2) and vice-versa?
<B> What is the value of using <$set> as in(4)?
<C> What is the use case for hard-coding rather than transcluding a filter
list, as in (3)?
Thanks!

(4)
<$list filter="[tag{!!title}]">
<$set name="testVar" value=<<currentTiddler>>>
<<testVar>>,
</$set></$list>
```
<$list filter="[tag{!!title}]">
<$set name="testVar" value=<<currentTiddler>>>
<<testVar>>,
</$set></$list>
have fun!
