Only the code may be more complete reference than backend-specific 
sections in the manual. There are some issues (e.g. cross-file id 
links), but in general links should work.

It seems ::search part is stripped. Perhaps ::#anchor should be exported 
as #anchor, however it is more tricky with line numbers or text search 
variants.

I have tried

Par <<label>> and [[#cust][link]]

* H1
:PROPERTIES:
:CUSTOM_ID: cust
:END:

[[file:t2.org::#anchor]] stripped.
[[file:t2.org#anchor]] retained.

[[label][link]]

and I get

Par \label{org59ae2bf} and \hyperref[sec:orgd12b09a]{link}
\section{H1}
\label{sec:orgd12b09a}
\url{t2.org} stripped.
\url{t2.org\#anchor} retained.

\hyperref[org59ae2bf]{link}

Beamer is derived from LaTeX. In ascii links to headings are supported, 
but <<anchors>> have no obvious way for export. As to formatting, see 
the following recent thread:
