Shift-click: Opens a link in a new window (just like right-clicking and selecting "Open link in new window")
Shift-middle-click (or shift-ctrl-click): Opens a link in a new tab, and switches to that tab immediately
Alt-click: Saves the contents of a link to your computer
With these shortcuts, you can quickly handle links no matter how you wish to use them. Enjoy!
