#Google Chrome Language, 2 keystrokes
<c-S><c-C>
Based on this Notepad++ answer.
Google Chrome supports Javascript (which in turn supports RegExp), so I hereby claim it to be a superset of Javascript and a language of its own.
How it works:
Ctrl+S
will invoke the "Save Page" dialog with the "New Tab" text pre-selected, Ctrl+C
will copy it into the clipboard, displacing the previous content.
Sidenote:
You can access the Javascript functionality in Chrome, via
javascript:
URLs and the Developer Tools console (invoked with Ctrl+Shift+J)
