How do I indent a paragraph (faster) on both sides on Pages?

I have many paragraphs that I need to indent 1 in. on each side.

What I’m doing is clicking the beginning of the paragraph, then setting the left and right indents to 1 in.(from the Text Inspector), then hitting return, then setting the indents back to 0 in. so that I can continue with my work. I know the shortcut that increases the indent level, but it’s for the left indent only.

Not only am I new to iWork, but I don’t even think I know how to do this on MSW. What is a faster way to accomplish this? It’s really effing with my flow lol
