As you didn't give much information as to what you were doing, I provided a basic way to indent a paragraph and at the same time change justification. I certainly did not say that that was the only way to do it.
If you had asked for simple indenting, without justification changes, then use the Increase or Decrease Indent buttons. They can be used with the cursor anywhere in the paragraph.
If you regularly require a particular paragraph format, just create a paragraph style and apply it as required. This can include not only indents, but space before and after the paragraph, font size and typeface and more... all applied in one go.
For a quick copy of a complete paragraph format including indents, font size and typeface etc., use the Format Painter button. With your cursor anywhere in the paragraph with the required format, click the Format Painter button, (the cursor changes to a brush-shape, move the cursor to the paragraph to be formatted and click.
I am not an expert on MS Word, just a regular user, so there are likely other possibilities.
I have used WordPerfect as well and there are many differences. It takes time to adapt to the different ways of doing things. Just don't expect Word to work the way WP does - it's a very different program.
Type "using wordperfect and word" into the help search box In the Using WordPerfect and Word help page, look at Tools and Tips at the bottom of the page.
