You can solve the problem by cutting a large opening in a basement wall and adding a window that meets code requirements for egress. You'll find contractors willing to do this work, often for between $2,000 and $3,000, or you might consider doing it yourself.
Caps Lock is a button on a computer keyboard that, when pressed, causes all letters to be generated in capitals until deactivated. It is located in the position of a similar Shift lock key (and sometimes a Ctrl key) found in some other keyboard layouts. It is usually a toggle key: each press reverses its action.
As for The Fn key on mac keyboards is a hardware driven feature -- I was tempted to state that as well, but: the keyboard viewer in fact knows when this key is pressed. That made me think it's not that different from, say, the Shift key... â Arjan Nov 6 '09 at 20:18.
