I don't understand. Are you asking about switching from "Latin" Left-to-Right languages to "Semitic" (Arabic, Hebrew) Right-to-Left languages? If so, Camtasia is NOT user-friendly to this. Camtasia 8 allowed you to use "Legacy" annotation boxes that permitted RtL, while the newer (and 2019) have a harder time. If you make a mistake, you have to type in the entire annotation again - it's very hard to trick Camtasia, which is not built to accept RtL.
