I have gone through the Keyboard Shortcuts for Google Docs page — didn't find what I was looking for there — and have added the AutoControl Shortcut Manager extension to Chrome.
After a brief review of its framework, it appears to me that I will have to write a script that would execute the action of creating a new blank document.
Before I begin this process, I thought I would check if there is anything I have overlooked. So.
Is there a keyboard shortcut to create a blank document from the docs.google.com/document/u/0 webpage?
I searched the website and couldn't find anything specifically about creating a blank document.
