How can I create, in an org mode file, a link to a second-level heading located in another org mode file?
I can do this for a first-level file with
[[file:external-file.org::*first-level heading][description]]
but I haven't been able to find a way to do this for second level headings. I've already tried with
[[file:external-file.org::*first-level heading**second-level][description]]
[[file:external-file.org::*first-level heading/**second-level][description]]
[[file:external-file.org::*first-level heading::**second-level][description]]
and none of them work.
The documentation says this:
file:projects.org::*task title
heading search in Org file
Note that this says "heading search", not "level-one heading search". No mention is made of the number of asterisks having to match the heading level. In your example, this should work:
[[file:external-file.org::*second-level][description]]
