Specify the abbreviations or letter combinations that you do not want LibreOffice to correct automatically.
The exceptions that you define depend on the current language setting. If you want, you can change the language setting by selecting a different language in the Replacements and exceptions for language box.
Select the language for which you want to create or edit the replacement rules. LibreOffice first searches for exceptions that are defined for the language at the current cursor position in the document, and then searches the remaining languages.
Type an abbreviation followed by a period, and then click New. This prevents LibreOffice from automatically capitalizing the first letter of the word that comes after the period at the end of the abbreviation.
Lists the abbreviations that are not automatically corrected. To remove an item from the list, select the item, and then click Delete.
Type the word or abbreviation that starts with two capital letters or a small initial that you do not want LibreOffice to change to one initial capital. For example, enter PC to prevent LibreOffice from changing PC to Pc. Enter eBook to prevent an automatic change to Ebook.
Lists the words or abbreviations that start with two initial capitals or small initial that are not automatically corrected. All words which start with two capital letters or small initial are listed in the field. To remove an item from the list, select the item, and then click Delete.
