The most popular word processors, such as Microsoft Word, LibreOffice and Googlr Docs, all include correction tools (often called Autocorrect), which automatically replace certain typed sequences of characters with other characters. These tools are language specific so, if you use them, make sure they are correctly configured. Otherwise, you may find yourself unable to enter a correct sequence at all, because they will unhelpfully change what you type.

Automatic substitution of characters may be a useful option, if set up in accordance with the way you want to work. It can include the following:

1. Correction of common typing errors (such as teh to the or abotu to about)
   
   
2. Automatic suggested completion of long words
   
   
3. Expansion of abbreviated forms
   
   
4. Substitution of character sequences to access special characters, such as a double hyphen replaced by an em dash or 1/4 replaced by ¼
   
   
5. Replacement of unlikely sequences, such as double capital letters at the beginning of a sentence replaced by a single capital letter
   
   
6. Automatic formatting of lists
