[nabs-l] Gmail Undo Button question

[Kaiti Shelton]

HI all,

One of my roommates just told the rest of us that GMail has an "undo"
feature. In the standard version of Gmail, this option can be turned
on by going to settings>labs>enable send undo (I believe that last one
is correct but I know the first two steps are right).

I'm pretty careful to check emails before sending them to my
professors, but it would be a cool feature to have if it can be turned
on in the basic HTML version of gmail.  My roommate says she's used it
when she finds a spelling error after she's sent an email, so she can
"Undo" the send, fix the error, and send the message again.  For her,
the "Your message has been sent" banner is where the undo button shows
up.

Any ideas how to do this?

Thanks,
