\useexternaldocument

Syntax

 \useexternaldocument[...][...][...] [...] name [...] file [...] text

Example

Assuming that the file « intermezzo.pdf » is present in the same directory as the document you are typesetting, the following allows you to open the file upon clicking on the link

```\setupinteraction[state=start]
\setupcolors[state=start]

\useexternaldocument[intermezzo.pdf]

\starttext
As one may see in the example \goto{ open the file intermezzo}[file(intermezzo.pdf)].

\stoptext

```

As a matter of fact many other file formats are recognized. It is also possible to give the path of the file to be opened.
