Why being a righty rules.

If you’ve got more than one tab open in Firefox, and you’re closing the entire window: You move the mouse over the icon in the top left corner of the screen and double click it. Firefox says “Lotsa tabs… really close window?”, so then you move your thumb over to press the Enter key on the numpad. Window Closed. When this technique is perfected, you don’t even see the dialog box 😀
