Here's what it means in practice:
* The flagged word remains unchanged. It will not be corrected, even if it's misspelled.
* Any other occurrence of that same word will also be ignored. The spell checker will not flag them for potential errors.
* This setting only applies to the current document. If you open a new document, you will need to make the "Ignore All" selection again.
Important Considerations:
* Use with caution: "Ignore All" is a powerful tool that can save time, but it can also lead to errors if you're not careful. Only use it when you're certain the word is spelled correctly in all instances or when you intentionally want to use a non-standard spelling.
* Review later: If you're unsure, it's often best to manually check the occurrences of the word before ignoring all instances. You can always go back and edit the document later if you find errors.
* Consider context: Sometimes, a word might be flagged as misspelled because it's used in an unusual context. In these cases, you might want to add the word to your personal dictionary, which will ensure the spell checker doesn't flag it again.
Ultimately, the decision to "Ignore All" is up to you, but it's important to understand the implications of this choice before making it.
