Steve got an old hand-me-down laptop, and he can't log into it with the password. Then he realized that the password was reversed because the monitor was actually "backward." Leo says that some regions in the world read right to the left. What likely happened is that a keyboard shortcut was used (CTRL right shift), which changed the keyboard orientation. It's really easy to do and it makes the text orientation move from right to left.
So, going with CTRL left shift will move it back to "normal" (English/US region).
