Answer:

In a word processor such as Writer, you can find all of the characters that are not available to type in the document by going to the "Insert" menu and selecting "Symbols" or "Special Characters." This will bring up a menu with a variety of shapes, symbols, and special characters that you can insert into your document. Alternatively, you can also find these characters by going to the "Format" menu and selecting "Characters and Styles" or "Font."

The exact name and location of the menu option may vary depending on the version of Writer you are using. However, it is usually located in one of the menus mentioned above.

You can find all such characters that are not available on the keyboard in the "Symbols and Special Characters" option in Writer.

To access this option, follow the steps given below:

Open LibreOffice Writer.

Place the cursor where you want to insert the special character.

Click on the "Insert" menu in the top menu bar.

Select "Special Character" option.

In the "Special Character" dialog box, select the "Symbols" or "Special Characters" tab.

You can browse through the different symbols and special characters by scrolling through the list or by using the search bar to find specific characters.

This option provides a wide range of symbols and special characters that are not available on the keyboard, such as currency symbols, mathematical symbols, arrows, and many others.
