By default, when we use a text box, there is a certain distance between the text in the text box and the border line of the text box. However, sometimes we just can't type a word or two because of the need, such as the size of the text box has been fixed and can't be changed. At this time, we can cancel the default text margin, and achieve the purpose of typing the text completely without changing the size of the text box. We often use this function, which is very practical. The method is as follows:

1. Click to select the text box to be set, right-click and select "Format Text Box" in the pop-up right-click menu.

2. The Format Text Box dialog box appears, and click the Text Box option.

3. Under the "Internal Margin" option, change the left margin, right margin, top margin and bottom margin to 0, so there is no gap between the text and the text box. Of course, we can also change only one of them to 0, especially the right margin, which used to have the enter symbol, but after changing it to 0, there is no such enter symbol. Finally, click OK.
