[Orgmode] Hyperlink to a string in an external text file

[Steve Hafner]

According to the Org manual a link to an external org file can have
the form "file:projects.org::some words" to allow a hyper jump to the
first occurrence of "some words" within another org file. But why
restrict this to org files? It seems this should work with any text
file; and when I try the same thing with a LaTeX file, for example,
"file:file.tex::\label{theorem-B}" where "file.tex" contains
"\label{theorem-B}", it seems to work in the same way as for an
external org file. Is this a feature I can rely on for any arbitrary
text file?
