SysReq has to be the most useful key ever if you enable the MagicSysRq key in the linux kernel. From it, you can sync your harddrive, unmount everything, reboot, reset the video, or the most useful: kill all tasks owned by current tty.
Because of it, I can recover from most 'frozen computer' states. Those that I can't I can atleast sync and unmount my harddrives to make the chance of dataloss much less.

It looks like minimizing 5 windows in succession throws about 100 pages/sec for about 4 or 5 seconds, typically. My paging file utilization increased about 1/10 of 1%. I looked at my disks queue length, and it stayed at 0 througout the spike. My processor utilization went from under 5% to about 12 or 15%, and my processor queue jumped from 2 or 3 up to around 7 to 10 -- but both spikes were for a fraction of a second, unlike the paging spike.

It's also completely egotistical for them to bear the Microsoft logo. A modifier that is intended for window operations is actually a good idea (although better uses like Windows+Drag to move a window are for some reason quite absent), but making it the logo of a company is completely ridiculous. The menu key is also woefully underused. To be honest, with all the push towards using the mouse as a sole input device, these buttons would almost be better off on the mouse instead of the keyboard.
I'm surprised so many people voted for SysRq... although it's not used very often, it's extremely useful on Linux if you enable Magic SysRq keys when you compile your kernel (Why is this considered a debugging option? This should ALWAYS be enabled. I suppose it's possible to hit these combinations by accident, but it seems quite unlikely to me). Scroll Lock is used nicely in MESS to switch between controlling the emulated computer and controlling the UI. Print Screen isn't as useful to me, but in newer versions of Gnome it will actually take a PNG screenshot of your desktop. Kind of a modern print screen.
Alright, the Pause/Break key isn't very useful... For some reason, nothing ever thinks to use it much anymore. Every game should allow you to pause using it, and I personally think that OS's themselves should use that key to suspend or kill programs when you use it. Maybe I'll remap it to give a Ctrl-C in Linux... This key always reminds me of the old Run/Stop key on my old C-64.
One key that I always thought was rather useless was the Num Lock key... at least on desktop machines anyways. Aside from laptops, pretty much everyone has cursor keys right next to the keypad, so I don't see much reason for duplicating their functionality anymore.
Personally, I'd love to have a keyboard with Super, Hyper, and Greek modifier keys. I actually hacked up a Greek font and used some Linux commands to let me do things like LeftCtrl-LeftAlt-L to get a lambda and such. This was actually quite useful while I was taking engineering classes, although moving stuff to a different computer didn't work too well.

With SysReq you can start a secondary sign on, end your current requested operation, work with your current job, display system messages, sign off, and various other functions. Very useful shortcut for AS/400 power users.
We also use IBM 4690, an OS for controlling IBM POS terminals.

That makes your right windows key become F13. Use xev if you wanna experiment with the left one. You'll have to restart X11 or manually load the new settings with xmodmap for them to take effect.
Now, go into your GNOME or KDE settings and figure out how to make F13 control the raising and lowering of windows under the cursor. On Ximian XD2, you'll have to go to the System menu, then Personal Settings, and then Shortcuts. Then you'll have to uncheck "Support MS Windows (tm) Keys". Then, look through the list for "Raise obscured window, otherwise lower" and bind it to your windows key (F13).
Now, try it.
Doesn't that feel good?
Of course, it works better with Focus-follows-mouse mode. For those of you that don't know, focus-follows-mouse is the setting that focuses the window your mouse cursor is over. New linux kids are so used to clicking to focus now, they don't seem to "get" the power user mouse behavior.
Then again, they also don't understand the power of a good virtual desktop pager (and no, neither KDE nor GNOME have one). Anyone who's used and loved FVWM2 or at least one of the FVWM variants knows what I'm talking about.
