How to change the regional keyboard input

Sometime, my computer is changing the keyboard settings (supposedly after hitting a sequence of keys without intent) and I am ending up with strange characters showing up when I am typing, either on Internet Explorer or in a Microsoft office document. For example, " instead of @, É instead of ?, etc...

Reverting to the normal input is tricky but here is the solution (here for Windows Vista):

- Go to the Control panel

- Open the Clock, Language, and Region

- Open the Regional and Language Options

- Select Keyboards and languages

- Click on "Change keyboard"

- Open the tab "Advanced Key Settings"

- Now you can select shortcut to switch between keyboard settings, such as Ctrl+1 and Ctrl+2 by selecting the language and clicking on "Change Key Sequence"

- Click Apply or OK and you're done!!

If you're locked in a strange language, you just have to hit the shortcut (Ctrl+1 or Ctrl+2) to come back to the original language...
