Mac os X - locked outside my account (language!) Today I was cleaning my MacBook keyboard (OSX 10.6.6) while the user was locked.
Due to some random key-presses, the language of the login changed from English to Hebrew (I use both in MAC, but only English for login).
When in the login menu, the cmd-space shortcut has not effect, and it does not change the language.

I didn't have any way to change it, and was practically locked outside my account.

What is the magical key-sequence that can change the language back to English?

(for completeness - I did a hard reboot, which brought me back to the main login screen, and luckily the language reverted back to English...
Now I have changed the login preferences so that the language selection appears in the login screen anyhow, but the question is very important for anyone who found himself locked out.)

and also This Question, that is very useful if you are not already locked - so you can set the language drop-menu to appear also in the login menu.
This adds the language selection to the login window:


From the Apple menu, choose System Preferences.
Click Users &amp; Groups to display the pane (or choose User &amp; Groups from the View menu).
If the lock icon in the lower-left corner of the window is closed, click it, then enter the name and password of an administrator to unlock it.
Click Login Options.
Select the "Show Input menu in login window" checkbox.
