"Full Page Screen Capture" is imperfect, but perhaps good enough too

At https://chrome.google.com/webstore/ one may search for "screen capture" to find "Full Page Screen Capture" which is a plugin in that will screen capture Google Chrome while also scrolling down the scrollbar to get everything and not just what you immediately see. You press Alt-Shift-P to make it go. It doesn't lose anything, but you will notice some choppiness where is struggled to scroll the scrollbar, etc.
