The ALT-Print Screen method CH offers does not involve your mouse or the Explorer window. Press the ALT button on your Keyboard and while holding this, tap the PRINT SCREEN button on your keyboard. This copies the current window to the clipboard.
Then open the paint program, click EDIT > PASTE or something similar (look for paste)
Alternatively, you can right click within IE, choose SELECT ALL then hold the CTL key (on your KB) and tap the C key once.
Switch to MS Word (if you have, or another word proc) and hold CTL key and tap the V to paste the page here. Edit away.
The Word method allows you to change text at will and manipulate pictures a bit easier than Paint.
