Hold the left mouse button to select multiple links by drawing a selection rectangle around them, releasing the button will open them in background tabs.
-Hold the Ctrl or Alt key to open the links in a Stack.
-Bigger links have priority over smaller/nested links, hold the Shift key to select all links inside the rectangle.
Text selection has priority over the extension behavior, so draw the rectangle in an empty area.
Copying the links to the clipboard will be added after Opera implements the Clipboard API [ Probably on Opera 12.1/12.5 :) ]
