Is there a keyboard shortcut for downloading a screenshot?

[Rav]

Using Firefox 83.0 under Windows 10. When I want to take a screenshot
of a web page, I use the Take a Screenshot feature, which you can get to
either by clicking the three horizontal dots in the URL bar and then
selecting Take a Screenshot, or with the Ctrl+Shift+S keyboard shortcut.
I'm much more keyboard-oriented, so I use the shortcut. I then drag
the mouse to select the region I want. Firefox then displays three
buttons: X (to cancel), Copy (to copy the screenshot to the clipboard)
and Download (to download the screenshot to a .PNG file in the downloads
folder). I want to Download. While the cancel button has the keyboard
shortcut Esc, and the Copy button has the keyboard shortcut Ctrl+C, I
can't find a keyboard shortcut for the Download button. I've looked at
the lists of shortcuts at support.mozilla.org and developer.mozilla.org,
but don't see one listed for that. Is anyone aware of a keyboard
shortcut for the screenshot Download button? Thanks.

Download is selected by default, so you can just hit Enter.

Wow, I hadn't noticed that. Thank you!
