Feature summary (what you would like to be able to do and where):

• Hotkey to mark articles and redirects as reviewed. Should not be a toggle, should only be to mark something as reviewed (not unreviewed).

Use case(s) (list the steps that you performed to discover that problem, and describe the actual underlying problem which you want to solve. Do not describe only a solution):

• Redirect reviewing.

Benefits (why should this be implemented?):

• Quicker

Easiest way to implement may be to add accesskey="[letterGoesHere]" to a hyperlink somewhere. There's some utils such as resources/src/mediawiki.util/jquery.accessKeyLabel.js that kick in if you use the accesskey param on a link, I think. The exact keypress combination varies by browser and OS, but for example, accesskey="r" would make Alt-Shift-R work for me on Windows 10 + Chrome.

R is already taken by recent changes, so would need to pick a different letter.
