How can I disable Ctrl+Shift+Arrow from causing my screen to flip?

Windows 7 Home Premium, Catalyst Control Center.

Without any apparent reason, after booting my PC, I got this little balloon "HD 4600 Drivers updated". I did not install any new cards or drivers or anything.

But now, when I try to select an entire word by pressing Ctrl + Shift + ← / → my screen flips left to right and upside down.

Where can I disable this annoying shortcut?

OR

Any other way of selecting the entire word?

There is no option for this in Catalyst Control Center.

I just ran into this exact issue, and found the solution. I use CTRL+ALT+DOWN to duplicate a line of text in Eclipse, so when it flipped my screen I was somewhat perplexed :) My OS is Windows 7 64-bit and here is where the hotkeys can be edited or disabled.

1. Open Control Panel
2. Click on "Appearance and Personalization"
3. Click on "Display"
4. Click on "Change Display Settings" in the left
5. Click on "Advanced Settings"
6. Click on "Intel Graphics and Media Control Panel" tab **
7. Click on "Graphics Properties" button
8. Select "Advanced Mode" and click "OK"
9. Click on "Options and Support" in the bottom-left of the dialog

And voila! You can now change or disable the hotkeys.

This is specific to Intel graphics cards, and if your video card is not Intel then this tab will not be there and the instructions from this point onward will not be useful!

If you have an Intel graphics processor, you can right-click on your desktop and select Graphics Options > Hot Keys > Disable:
