Can an aside open in another tab?

[Barbara Ericson]

How do I get an aside to show centered in the page and have it display the datafile in it in another tab?

I don't believe that an aside will open a file in another browser tab. 

I used dataurl in py4e-int openingFiles.ptx to open the file in a new browser tab:

<p>Click <dataurl filename="mbox-short.txt" source="files/mbox-short.txt">here to view the mbox-short.txt data file</dataurl> in a new browser tab.</p>
