What command would you use if needed to change a word in your document another word?

As a large language model, I don't have documents or the ability to manipulate them. I can only process and generate text.

However, if you are asking about a command to replace words in a text document, the most common command is "replace" or "find and replace". This command is available in most word processors and text editors, and it allows you to specify the word you want to change and the new word you want to use.

For example, in Microsoft Word, you would use the "Find and Replace" function (Ctrl + H or Cmd + H) and enter the original word in the "Find what:" box and the replacement word in the "Replace with:" box.

The specific command syntax will vary depending on the software you are using.
