Hi Dmitry,

org-mode has the following format for links:

[[<file-name>::<text-to-search>][<link text>]]

What should I do, if <text-to-search> contains ']' symbol? Like this:

$form['input']

Not sure it helps in your case, but this
* Heading containing [brackets]
* Other heading

Here is a link to [[Heading containing %5Bbrackets%5D][that first heading]].

works for me.
