There is a slider with paragraph indentation on the ruler. The first line of the upper inverted triangular tube is indented, the lower tube is indented, and the lower tube is indented. If it is a completed document, you can use regular expressions or functions such as "Select similar format text" to select it at one time and adjust it at one time.

Select a reference, modify the paragraph format, change it to hanging indent, and adjust the indentation size. The simple way is to drag out the indented mark on the ruler above.
