Or, if you have the right kind of keyboard, you can do it this way:
1. Press and hold CTRL while you select "Print Screen" (which is usually on
the top row of the keyboard, to the right of the Function keys. It usually
says something like "Print Screen/SysRq"
2. Then open Word or Excel and select "Paste". Your screen print will be
pasted into the document, which you can then save and send.
Hope this helps! Good luck.
