I'm using Mozilla Thunderbird for my e-mails, but I can't seem to find a way to do this with my keyboard only:

  1. I press Ctrl-N to compose a new e-mail message
  2. I type in my first recipient's e-mail address, and hit Enter
  3. Now the cursor is on the second line, for the second recipient - but I'd like to make this a Cc: (not a To:) recipient.....

How do I do that, with my keyboard? I'd prefer not to use the mouse at this point... is there a shortcut for this? Can't seem to find any reference on how to do this.... anyone?

In a recent new build, the shift-tab functionality no longer works. I do this keyboard sequence frequently and for some reason it no longer is supported. This is a disappointing accessibility issue. – docSquale Sep 7 '13 at 15:20

After step 2 (after hitting Enter), Shift-Tab will highlight the "To" button. Press down arrow to change it to CC and Tab again to move to provide the CC address.
