How do you "Navigate Backward" and "Navigate Forward" using the keyboard in Visual Studio?

This may seem like a simple question but I have been using Visual Studio (different editions but Professional mostly) for years now and never figured what the hell is the keyboard shortcut for navigating forward/backward. I have tried a lot of different combination (including ['Ctrl' + '+'] or ['Ctrl' + '-'] but this did not work and after browsing several threads on the subject I never had the answer. I must mention that I use an AZERTY french keyboard, maybe the shortcut is broken for this configuration?

Solution

If you look in Tools | Options | Environment | Keyboard for the shortcuts for View.NavigateBackwards and View.NavigateForewards (here, respectively, ctrl - and ctrl shift -).
