New GMail message composer - keyboard shortcuts strongly improved

I use GMail daily and keyboard shortcuts are helping me to do things quickly.
Today GMail proposed me to use new compose window and I have learned, most of my wishes are fulfilled now.
So far, I missed couple of keyboard enabled features which I need daily:

1. change "From" to other then my default "sent from" address
   (Ctrl-Shift-F)
2. Add "CC" or "BCC"
   (Ctrl-Shift-C or Ctrl-Shift-B)
3. create numbered or bulleted list)
   (Ctrl-Shift-7 or Ctrl-Shit-8)
4. modify nesting of list items (indent, unindent)
   (Ctrl-] and Ctrl-[)

Other things, like insert link (Ctrl-K), format text bold (Ctrl-B), italic (Ctrl-I), underscore (Ctrl-U), were already there.

Keyboard shortcut for Delete concept is still missing.

Finally, Ctrl-Enter sends the e-mail out (before, I had to be in compose window and had to use sequence Tab, Enter)

Tips:

• If GMail offers you an explanatory help page for switch to new type of compose window, but the target help page does not exist (like for me, having default language "Czech"), switch language of help to "English" and you will see more.
• Get PDF with Search and keyboard shortcuts
• When in windows with list of e-mails, then use "?", to show help screen with all shortcuts
• Check tooltips of formatting icons - shortcuts are mentioned there too.

Thanks for these improvements.
