I love my Dell M3800 but shortly after unboxing I realized that there was no PAUSE/BREAK key on the keyboard so breaking into code was not looking good.
I eventually found a registry hack to re-map another key on the keyboard, but then I loss the functionality of that key.
Finally a co-worker of mine discovered that pressing CTRL+Fn+F12 = CTRL+BREAK!
