I think you need to have installed the ID ME version or use a plug-in like the one from In-tools.com
@Ellis home – are you refering to the "World Tools" for InDesign from In-Tools?
There seems to be no explicit version for InDesign CC…
Just CS5, CS5.5 and CS6 (Mac or Win).
Anyone with a subscription to CC can download one of the versions that supports RTL languages....
@Laubender - Yes, that's the one I was talking about. Didn't know it didn't have support for CC.
@Peter - You're right Peter. I guess you can download the English-Hebrew or English-Arabic under Apps. Haven't done it myself, but eventually I'll need it too. Thanks for the reminder.
