[Typo3] Page Alias in Constants Field

[David Pratten]

Dear All,

I have the following line in a Template Record Constants field:

pidSharedContent = 17  #pageid from which to draw shared content

I would like to replace the 17 with the target page's Alias which is
"Shared"

I have been unable to find a reference to this possibility in the
documentation.

How do I do it?  (He asks with the newbee's confidence that *everything* is
possible in TYPO3)

Thanks

David
