# Re: [tw] Re: [TW5] Desirable core additions

It's better if you explain what it is that you want to accomplish than
insist on how it gets accomplished. 

The variable <<currentTiddler>> is available to all "children" of a
tiddler, assuming that by children you mean transcluded or templated
tiddlers. If you have some other interpretation of what children are, then
you need to explain what you want to accomplish.

If you have a tiddler with several transclusions, and then clone that
tiddler, all the transclusions of the clone will then use their
<<currentTiddler>> value.

Good luck,
Mark
