Hi, Bo.
Ya gotta remember, there were computers long before Windows XP - or even
Windows or even Microsoft. Some (no, not all) of those original computers
had keyboards. Many of the keys on our keyboards are simply historical
("legacy") holdovers from the days of typewriters, teletypes and other
predecessors of what we use today. Some of them don't really make sense
anymore, but the keys are still there, still with their original labels.
Skipping forward to today... The Pause/Break key is usually just about the
upper-right-most key on most standard keyboards. Just like the typewriter
number keys, you get one result if you hold down the Shift key while
pressing this one, a different result if you don't. Only, for this key, use
the Ctrl key instead of the Shift key. The original idea was that the Pause
button would stop the program from running until you pressed some other key
(Enter?) to make it go again. The Break key would interrupt the program
completely and exit it, returning control to the operator. Those keys still
work that way most of the time, but some programmers have programmed around
them. And other programmers have added functions.
For example, they added the Windows logo keys (between Ctrl and Alt) on the
"Natural" keyboards built for Windows 95 and added some functions that this
new "Win" key (or "WinKey" or "Winkey") could do. Now, pressing Win+R opens
the Run prompt window; Win+E opens Windows Explorer (or My Computer). And
Win+Break pops up the System Properties page on your screen.
Just one of the many things that you learn in Windows 101. This is
explained in the Help and Support files on your computer. (Win+F1, or click
Start, then Help & Support - then Windows basics, Windows keyboard shortcuts
overview, then Natural keyboard shortcuts.)
Play around with these for a while. Lots of things to learn here. ;<)
