So you know the built-in keyboard shortcut on Windows that opens LinkedIn? (IIRC it’s Ctrl+Alt+Win+Shift+L)

That’s because Microsoft sold keyboards for a while with “Office keys,” so you could hit Office+W for Word, Office+X for Excel, etc. All that key would do is send all those modifiers. There are plenty of unused modifier key codes they could use instead, but they did this.

I’m guessing this key works the same.
