Unless you're a PC, in which case there are various keystroke commands.

And, for mac, you can capture a window of your selection with Apple + Shift + 4.

Hit all three at the same time.

PCs I've had sometimes have a button along the top row, but never the same on different makes.

Maybe, not sure, but rightclick screen cap? Hell I don't know.

Good luck!!!

sorry forgot to mention

It depends on the keyboard. I've got two in front of me. On one you have to use (fn) to hit (prt sc) and on the other (prt sc) is the primary purpose and use (fn) for (sys rq) - whatever that is.

Anyway, after you do a (prt sc), open up Paint and use Ctrl-V to paste it into the window. Then you can save it, print it, edit it, scribble on it, dribble on it, or whatever else you want to do.

That's Control-Print Screen. Laptops have dual use keys so that the print screen key is secondary to some other more common key.

This started from the olden days where Control Print screen would copy the monitor screen to the printer. All 40 rows at once. Shift print screen would start logging to the printer until you hit it again each line would print one at a time. Some old DOS versions will still do this if your printer is attached using a parallel port.

These days, outside of DOS, it goes to the paste buffer.

For a long time (fn)(f12) was (prt sc), but I haven't seen a keyboard with that on it for about a decade. I go back a long way with computers, but things change with time.

On edit: I'm using Ubuntu Linux

I remember somewhere having the instructions for doing the whole page (without shrinking the font so small I can't read it anymore)

dang, I would like to copy something before I shut down and go to bed.

How to do it will vary by OS and by browser in use, but it is possible.

I'm not a lot of help. Sorry.

Then you can paste it into paint and change it to a jpg with a save-as. Can also crop and zoom it before saving too.

I could have sworn there was a pretty easy way to do it (somewhere on another computer I have a whole long thread captured from DU2 - it was a hilarious thing that was going on during some glitch and people were haveing a lot of fun posting images of things that werent allowed normally)

I ended up making 4 jpgs of this tonight. (All afternoon I kept a tab open of my last look into Meta, decided to grab it for posterity)

if you still have the page available.

Or use the "Save Page As" and choose "Web Page, complete" and it will save the whole page including all the little icons and graphics and reconstitute it when you are offline.

If there's another way, I haven't learned it yet but would love to know.

Then paste it in an image editor.

It takes a snapshot of what is visible on the screen at the time and will not save the web page below the 'fold'.

To save the entire web page go to File/Save Page As and save as "Web Page complete (*.htm, *html). That will save the entire web page, including all the part you have to scroll to see. (ETA- the command will vary depending on your browser. I use FireFox.)

Another way to save a web page, though the formatting can be funky, is to "print" it to a PDF. I use this for printing informational pages since I can set my print choices in my browser to save the date I printed it, the URL and other information for reference.

I use the free program, Cute PDF Writer - http://www.cutepdf.com/products/cutepdf/writer.asp

Go to File/Print Preview to see how the web page fits (you can select a percentage of the original to resize the page to fit better), then select Print. The CutePDF program appears in the print dialog as a printer choice. Select it, then select where to save the PDF.

The disadvantage is that with pages with a lot of graphics, the PDF program can split images at the page breaks and sometimes also does that with lines of print. Sometimes I save a web page both ways - as a HTML to preserve the formatting, scrolling and images; and as a PDF to preserve the URL and date information for reference.
