No problem re: ranting. The Acceleration on the mac mouse is the second article on the same webpage. Not sure how that happened. I tried it again and it still shows the url for the second article on the page. Oh well. I will try this though I don't understand why I have to open the website in full screen in order to make the letters smaller so they can hopefully fit into a screen shot.
How to Take a Full Web Page Screen Shot on a Mac
1
Navigate to the Web page you want to capture. If the entire page isn't visible without scrolling, put the browser window into full-screen mode by clicking the double arrow in the upper right corner. This feature is available in Safari, Chrome and Firefox.
2
Hold down the "Command" key and press the "-" (minus) key to reduce the page size until you can see everything you want to capture without scrolling.
3
Press "Command-Shift-4" on the keyboard. The cursor changes to a crosshair pointer. Move the cursor to one corner of the web page, then press the mouse button and drag it to the opposite corner. The highlighted area indicates what will be copied. Release the mouse button. The Mac makes a camera shutter sound, and the highlighted area is saved to your desktop as a PNG image.
4
Move the cursor to the top of the screen. The Apple desktop menu appears. Click the blue double arrow icon in the upper right corner to exit the browser's full-screen mode. Press "Command-0" to return the browser magnification level to zero.
5
Double-click the screenshot image on the desktop to open it in Preview. Select "Export" from the File menu if you want to change it from PNG to another format like JPG or GIF. As I tried to follow their directions using the blue arrows in the upper right hand corner of the screen I noticed they are not there anymore. I guess just going into full screen using the green button on the left would work. Though if all I am doing is making the letters smaller on a webpage to fit it all in, I don't see why I would want to start with a full screen anyway.
I know none of your commands was talking about the full webpage, but that was what I was after.
********
As I said, all commands other than command-P... show ONLY what you
see on your screen, NOT any part of the page that's above the top or below the bottom.

Forget my ranting about movies. I was looking at the wrong part of the interface.
