Check spelling in OneNote for Mac

Microsoft OneNote for Mac helps you detect and fix spelling errors as you type. This can save you time and effort while keeping your notes error-free.

Check spelling and grammar as you type

When you type, OneNote automatically checks for potential spelling errors, and underlines the words you should check with a squiggly red line.

To check a misspelling, control-click the underlined word, and choose the appropriate option.

You can do one of the following:

• If available, click one of the suggestions to substitute the misspelled word.
• Click Ignore, to reject the error detection.
• Click Add to Dictionary, to make sure that OneNote doesn't detect the word as an error in the future.
• Click Smart Lookup, to do a quick Bing search on the word.

Check spelling on an entire page

To check spelling on an entire page, do the following:

1. Click Tools > Spelling.

2. In the Spelling pane on the right, do any of the following:

   • Click Ignore to skip the currently selected text and move on to the next item.
   • Click Add to add the currently selected text to the dictionary so that OneNote doesn't detect the word as an error in the future.
   • Select a replacement word in the list, and then at the bottom of the pane, click Change.

Check the spelling of your notes in a different language
