If you have one of the "specialty" keyboards, like the Microsoft Business keyboard that came with my computer, your computer probably boots with the "F" keys assigned to Help, Office Home, Task Pane, New, Open, Close, Reply, Fwd, Send, Spell, Save, Print, Undo, Redo.
You'll have an "F Lock" key that you can press to turn on an indicator light that means the keys do the normal F1, F2, ... etc.
But you'll also need to hit the NumLock button (which is labelled "Tab" on the Num Pad) to get the Num Pad to work, and if you don't do that, then the PrtScn button is actually an open-parens "(" which is sort of useless in that location so far as I can see.
A secondary row of buttons at the top lets you open Word, Excel, your browser, email, calender, Files, calculator, mute your speaker, or adjust the volume, log off, or put the machine to sleep, with each action needing only a single button push. There may also be a "scroll wheel" built in, usually on the left, with Fwd and Back buttons, Cut, Copy, and Paste buttons, and a Fwd/Back "Applications" button that acts like a Ctl-Tab/Shift-Ctl-Tab for switching between windows. The scroll wheel and Applications button both work nicely to transport you to random places when the cat tries to demand petting while you're at work, or when you move the book you're copying from and bump one accidentally.
I wonder if anyone ever actually uses all (or any of) that crap.
Of course since a recent (month ago) Microsoft update to the default mouse driver forces loading of the new "default" driver, none of the buttons work unless you open the "Microsoft Keyboard" program (which doesn't appear at keyboard in Ctl Panel) and "Reset" after each reboot.
Hooray for progress.
(Sure hope Art never sees one of them newfanglicated keyboards.)
