Pause/Break key on modern keyboards

Is there still a use for this key in modern operating systems? I know back in the days of the rapid fire dir /s on ten thousand files in DOS 5.5 this key was indispensable, but is it needed anymore? If not, can I remap it to do something else? If so, what?

In Windows, Windows + Pause/Break opens up the System Properties window. Not exactly relevant to what the key was originally designed for, but still quite useful!

The Pause/Break key can also be used during boot to pause a POST screen so you can read it before continuing. I find it useful when I'm trying to double check that something is detected properly by the BIOS.

Here are a couple common keyboard alternatives (please feel free to contribute to this list)

• General -Pause
• General -Shift + Pause
• Lenovo - Ctrl + Fn + F11
• Lenovo - Ctrl + Fn + B
• Lenovo - Fn + B
• Logitech - Fn + B
• Samsung - Fn + B
• HewlettPackard - Ctrl + Fn + Pause
• HewlettPackard - Ctrl + Fn + Right-Shift
• Dell - Fn + B
