I have been using the following script in Keyboard Maestro to promote/demote paras in Word (for various reasons it works better than a straight custom-keyboard shortcut).
tell application "Microsoft Word"
outline demote (paragraphs of selection)
end tell
(The parallel script uses outline promote.)
This was working fine for ages, including in the weeks since I upgraded to Mavericks.
Now, however, it fails, with an "Expected end of line but found identifier" error, with demote highlighted in ASE.
