How to change the text direction on Windows?
Solution 1:
To switch between RTL (Right-To-Left) and LTR (Left-To-Right) text directions, you need to click Ctrl+Shift:
Ctrl+Left Shift for
LTR.Ctrl+Right Shift for
RTL.
To change the direction of the whole text, select all of it (Ctrl+A) before changing the text direction.
Solution 2:
I struggled to fix a similar issue - it turned out to be limited to Office applications (inc. Outlook) and was caused by having Hebrew listed as an editing language (Options>Language>Choose Editing Languages).
Removing it and restarting all Office applications solved the problem.
