how to move a text to the right

Finally I have succeeded to create a paragraph tag with these settings (with an offset of 2 cm) :

Meanwhile, I have deleted this document and created a new FM document by importing the same Word file inside, and it worked (I can modify again the file).

But I have always the problem of adding an offset to the text (move the selected text to the right). How to set the paragraph (see red arrow) in order to have this offset ?

It seems to be unlocked :

If I try to modify something, FrameMaker says me : "modification impossible. Document for consultation only".

This text was coming from a Microsoft Word document.

Sorry but I don't understand what button to use ?

That heavy right arrow (🡆) is for Object alignment, not paragraphs.

You need to use the right para align button 1 row above and 2 icons to the right, or shortcut ␛jr

But this is not ideal document stewardship, as it merely applies an override to all the paragraphs, which will vanish when any of the formats are updated by various means.
