'Download' option shortcut

[Darkmaster006]

Okay so let's say I'm taking a screenshot of Facebook and I scroll down a bit, I'll have the top bar going along with my scroll and so I would have it hinder some part of my screenshot. So, what I need to do is scroll up until the bar is out of the screenshot, and then save the screenshot. But, when I'm up, I don't have the 'Download' button available (nor the 'Copy' one for that matter), so I'm always forced to do 'Ctrl + C' for copying, then get it into Paint, and save it from there. But is there really no 'Download' shortcut so I can simply download it directly with the keyboard? Thank you.
