When writing an e-mail message in Outlook 2010, pressing CtrlShift on the right hand side of the keyboard changes formatting to right-to-left (as would be required for e.g. Arabic, Hebrew, etc.). Same occurs in Word 2010.
The problem is, I never need right-to-left formatting — but I often press these keys by accident, and then my text gets formatted right-to-left, which is most annoying.
How do I disable this keyboard shortcut?
I have looked in Options > Language, and in Control Panel > Region and Language settings, but have not found any mention of this keyboard shortcut.
This question is similar but there is no unambiguous solution there, and my question does not deal with changing languages or keyboard layout.
