Mac, Password and local keyboard setting...

First time, just before to login to write this
post, I was stuck with Macbook, where
my user password in English character,
forgot to change keyboard back to English
(from Punjabi), while Close MacBook
(which I often do).
When I opened, it was asking for password,
tried 2-3 times, but failed, then I found that
keyboard layout is Punjabi (not English),
so it was not accpecting password.
I tried Keyboard Shortcut to change like
Fedora/Gnome did. (+ keys),
but it was not changing, Rebooted, but still
asking for password.

Finally I found solution, hard learning, but it
works
Press key + (also
key also w0rks).
may be helpful in very rare condition, but it is
working this way....
