On desktop devices you can use the alternative mouse button (the right-click) to bring up contextual menus. As an example you can use the alternative mouse button in a word processor and get to see different options to format text, insert a numbered list or create a hyperlink.
If we continue the example; when you use the same word processing application on a touch screen device (touch screen desktop or tablet), is it considered good practice to mimic the alternative mouse button click, and bring up the same contextual menu?
