1. Title settings for books, charts, tables, etc. Often inserted into documents. In typesetting, in order to facilitate searching and reading, a line of words such as "Figure 1" and "Table 1" is usually added above or below the figures and tables. At this point, you can use the caption function of Word 2007 to automatically add captions when inserting these charts. You can do this by clicking the Insert Title option in the Title Options area of the Reference Ribbon to open the Title dialog box. At this point, click the Auto Insert Caption button to open the Auto Insert Caption dialog box. In the "Add caption when inserting" list box, select the option of automatically adding caption, and you can select multiple options at the same time. Select the title tag in the tag drop-down list box. There are three kinds of title labels built into the system: chart, table and formula. If you want to use custom labels, such as Diagram and Table, click the New Label button and enter the custom label text. In the Location box, you can specify whether the title is below or above the project, and then click OK to finish the title insertion. After inserting these options, Word 2007 will automatically insert captions. 2. Footnotes and endnotes have been set. Footnotes and endnotes are used to explain, illustrate or provide reference for some contents in the document. Footnotes usually appear at the bottom of the page as a description of something in the document; Endnotes are generally located at the end of the literature to explain the source of the cited literature. Footnotes and endnotes can be contained in the same document. Footnotes and endnotes consist of two parts: annotation reference marks and corresponding annotation texts. You can have Word 2007 number labels automatically, or you can create custom labels. When you add, delete, or move automatically numbered annotations, Word renumbers the annotation reference marks. You can use any length of text in comments, format the comment text like any other text, and customize the comment separator to separate the lines of the document body and the comment text. The method of inserting a footnote or endnote in a document is as follows: in page view mode, click the position where you want to insert the reference mark of the note, and then click the option button of Insert Footnote or Insert Endnote in the Footnote option area of the Reference ribbon, and then automatically set the insertion point at the bottom of the current page or the end of the document, and wait for the input and formatting of the note. You can also click the small button in the lower right corner of the Footnote Options area to open the Footnote and Endnote dialog box, where you can make several settings. In the Location Options area, click the Footnote or Endnote radio button. Select the desired format under Number Format, or you can customize the label (click the Symbol button to select the symbol in the dialog box). Select the type in the number box. Select a range in the Apply changes to box, and then click OK to exit. At this point, Word will insert the comment separator in the footnote or endnote editing area, and put the insertion point in the corresponding position for you to enter the comment text. 3. Bookmarks are used to identify the location you specify and the selected text for future reference. For example, you can use bookmarks to identify the text that needs to be modified in the future, and use the bookmark dialog box to directly locate the corresponding text when modifying in the future, without scrolling up and down in the document. You can also add cross-references to bookmarks. For example, after inserting a bookmark in a document, you can create a cross-reference to the bookmark so that it can be referenced elsewhere in the text. This function is very useful for modifying and consulting long documents such as books. (1) To add or use bookmarks, you must first select the text or item to which you want to specify bookmarks, or click the location where you want to insert bookmarks. In the Link Options area of the Insert Ribbon, click the Bookmark Options button to open the Bookmark dialog box, and enter the book signature in the book signature text box. The book signature must start with a letter, and can contain numbers, but not numbers. Scroll to another place where you need to add a bookmark, and then add another bookmark. After adding a bookmark, just open the bookmark dialog box, select the signature of a book, and click the "Locate" button to immediately locate the insertion point at the location specified by the bookmark. (2) After changing the bookmark to bookmark a text block, Word will enclose the selected text in light gray square brackets as a mark, or an "I" character mark will appear at the specified position. If you want to change the bookmark item, you must make sure to change the text or picture in brackets. By default, bookmark tags are not displayed. To display the bookmark tag, you need to click the Microsoft Office button (the round button in the upper left corner), click the Word option, click Advanced, then select the Show Bookmarks check box under Show Document Contents, and finally click OK. You can change bookmarks, cut, copy and paste bookmarked items, and add and delete text in tagged items. (3) Delete Bookmarks Click Bookmarks in the Link Group on the Insert tab, click the book signature to be deleted in the pop-up dialog box, and then click Delete. To Delete the bookmark of an item marked with bookmarks, such as a text block or other element, first select the item, and then press the delete key.
