Applying changes in the projects made in Adobe InDesign

Hello!

I would like to know more about Adobe InDesign. What do you mean by threading text? How to do it? Give me instructions on how to do it? What about wrapping text around objects? Show me sample or provide me instructions on how to do it? Does it support different writing like Japanese, Arabic or any Cyrillic Symbols? Show me and tell me how to create bullets and numbering in this software? How can I make some adjustments? How do I find and change specific words or contents? What do you mean by Anchored Objects? Thank you very much and have a nice day!
