Check the Spelling of a Message in Mozilla Thunderbird, Netscape or Mozilla
To scan a message you are composing in Mozilla Thunderbird, Netscape or Mozilla:
- Select Options | Check Spelling... from the menu.
- Tools | Check Spelling... in Netscape 4.
If you find it hard to remember that spell checking is an option, maybe you have more luck memorizing the keyboard shortcut for this command:
- Ctrl-K on Windows, Alt-K on Unix and Command-K on a Mac.
While Mozilla does not come with a spell checker itself prior to version 1.5, you can easily install one.
