Launch PDF viewer from within a Mathematica Notebook

Question

I would like to view a designated PDF document by clicking on a hyperlink in a Mathematica notebook.

I am able to open the designated PDF document using SystemOpen["E:\OneDrive\Learning Mathematica\Tutorial.pdf"] which opens the document using the system default PDF viewer configured on my local machine. This is acceptable. My only problem is that I don't want to see the SystemOpen[] command in my notebook cell. I want to launch the PDF document viewer by clicking on a hyperlink (or something similar) which I am able to label with some user friendly text.

Answer 1

url = "C:\\Program Files\\Wolfram Research\\Mathematica\\11.3\\Documentation\\English\\
 System\\ExampleData\\mathematica.pdf"; 

Button[Style["mathematica.pdf", "Subsection"], SystemOpen[url], 
 Appearance -> "Frameless"]

To replace the input cell (url = ...; Button[...]) with the button object, highlight the cell contents and, then either (1) select Evaluate in Place from the Evaluation menu, or (2) use the keyboard short-cut Ctrl+Shift+Enter.
