The following options should be presented when long-pressing a link:
- "Open": open the selected link in the current tab.
- "Open in new tab": open the selected link in a new tab.
- "Copy address": copies the URL of the link to the clipboard, and shows a Snackbar that says, "Link address copied to clipboard".
- "Share": shares the URL of the link via the standard Activity chooser.
- "Save": save the target page (show the same sequence of Snackbars as when saving the current page normally).
