I have been messing with computers for 20 years, and I have been creating websites for more than ten. Believe it or not I never had occasion to do a print screen to create a screen shot before today. I guess I mainly worked with my own content.
However, I had a good reason. I was helping out a person writing to me at BreadInfo.com. I had a PDF file of the manual and wanted to show my correspondent the instructions for programming a Zojirushi. I could have sent the whole manual, but it is huge. So I decided to do the print screen thing. Little did I know how easy it would be.
Basically, in Windows XP, and probably most other windows systems, you just hold down alt and then hit the PrtSC key. This will print the window to the clip board. If you want the entire screen just hit the PrtSc button. You can then paste it to your favorite image editor and do what you like with it.
Well there is nothing like revealing your ignorance for making you feel young…and naive again.
