"SysReq/PrtSc, Scroll Lock and Pause/Break", I have never used those keys and in most cases cannot imagine what they do, LOL
The only thing that bothers me is that it puts the CTRL key down in the corner, which is a stupidity introduced by PC. Old UNIX keyboards (terminals) and my current (Happy Hacking) keyboard put it where the never used SHIFT LOCK is located on the X16 keyboard. Even the Commodore 64 got it in a better position (TAB) than down in the corner. Having it down there means I need to twist my hand to reach it, and I use that key a lot. It is actually very annoying to me, but I guess that I am the minority. (Rant off)
SysReq was intended to be a key to swap tasks (something like Alt-Tab is used for now.)
Scroll Lock does what the name suggests - it was intended to let the user use the arrow keys to scroll the screen. The introduction of the mouse kind of made that key redundant, however.
Pause/Break also does exactly what the name says. It blocks screen output, causing any program writing to the screen to Pause until another key is pressed. Pressing Control+Pause sends a Break message, terminating a running console program. It can also be used to send a Break signal to a mainframe, which does basically the same thing.
And I use the caps lock key Every Darned Day. Some days, it's on more than it's off... and I like it where it is, since having the Control key down low allows me to keep it uniform on both sides of the keyboard. And if you're contorting your hands to reach it, you should be using the control key on the opposite side of the keyboard.
