Question

I need to disable indentation in only one section of my document (subsection, to be specific). How can I do that?

Default indentation is provided by indentfirst package.

Answer 1

It depends on how pervasively you want to eradicate the indentation. But the first thing I’d try is setting \parindent to 0pt:

Some text with normal indentation...

{\parindent0pt % disables indentation for all the text between { and }

Text with no indentation.

Still no indentation.

}% restore indentation

Indented again.
