A few posters have sent me PMs about how to screen capture after the tutorial I tried to do for wannacorndog last week. I am attempting to make things absolutely clear. I am not going to attempt to explain the mechanics of how this works, just how it is done.
(Sorry mac users, figure it out on your own).
1. When you have something displayed on your screen press the key on your keyboard labeled "PrintScrn/SysRq". It should be above your arrow keys on in the same row as your F1-12.
2. When you press that key nothing obvious will happen, you won't be notified of success or anything like that so don't just sit there tapping it waiting for a beep.
3. By pressing that key you have saved a snapshot of exactly what is shown on your screen into temporary memory. Look up the windows clipboard for a better summary. (if after you have done it and you go to copy/paste some text your screen shot will be written over).
4. Open an image editing program. For the sake of ease I use MS Paint. Start>All Programs>Accessories>Paint. Open up paint and go to the edit menu (or right-click) and select "paste".
5. You should now have your screen shot. Don't forget to save it while you are looking at it in an image editor.
The default format of a screen capture isn't very friendly for forum posting so make sure you change the file type to .jpeg (or whatever you like).
Enjoy.
