Tutorials? World Tools Forum

I've downloaded and installed the WorldTools Pro plugin for InDesign CC 2014 x64, and I can see all the dialogs and menu items that are now present in InDesign, but I have no idea how to use them. I need to typeset in Arabic (right to left) and willl have a native speaker assisting me, but I need to have some idea how to make this work before sitting down with her.

How do I begin typing in Arabic? I see Arabic fonts on my system, but when I create a paragraph frame and begin typing in it, it's left-to-right, Roman characters, no matter what I have selected in the World Tools ME dialog. I'm clueless as to how to actually get Arabic, right-to-left working and how to type in Arabic using my standard QWERTY keyboard. I'm sure I sound extremely stupid, but so be it. Is there any help file that contains guidance on getting started for someone like me? Is there a keyboard overlay plugin or something that will allow me to type in Arabic?

I'm on the 20-day trial as of this morning, and I want to make sure I can actually use this before purchasing. Can anyone help the stupid guy get going here?

Grateful for any help.
