I found a solution to this issue on the OfficeMac forums, but the post (or entire forum?!) had been removed some time ago. Luckily, Google had a
cached version of the page from which I was able to extract the instructions provided by user "fafa." The updated summary of these instructions is as follows:
1. Make a backup of ~/Library/Preferences/com.microsoft.Word.plist
(Command + Shift + G from finder, paste in "~/Library/Preferences/" and click "Go", find com.microsoft.Word.plist and make a copy of it somewhere you can find it)
2. Open Terminal and paste the following:
Code:
defaults write ~/Library/Preferences/com.microsoft.Word.plist NSTextInsertionPointBlinkPeriod -int 500
The number at the end is the speed of your cursor in milliseconds; 500ms is the speed the cursor blinks in all of Apple's normal applications. I tested this myself and found it to work in Word 2011, even though the original guide was from Word 2008.
3. Restart Microsoft Word.
That's it!
