Hi John,

This feature does exist, and your guess at the syntax is almost correct.
To reference a variable named foo1 in a file named foo.org you would use
the following syntax, ":var data=foo.org:foo1".

See the attached foo.org and bar.org files for an example (in order to
work they must be in the same directory).

I'll make a note to mention this functionality in the documentation.

Best,
