Update to the GMail Keyboard Shortcut graphical cheat sheet
Thanks to a post over at the Google Operating System blog I became aware of a couple new keyboard short-cuts when using GMail.
The two now short-cuts aren’t documented but they work as advertised:
- b will create a new e-mail with both the CC and BCC fields displayed, while
- d will create a new e-mail with the CC field displayed.
You can’t use the short-cuts after you’ve already created a new e-mail.

You can find them in the updated GMail Keyboard Shortcut graphical cheat sheet.
