Try this in TextEdit, or any Cocoa app (make sure that “Check Spelling as You Type” is enabled).
- Type “/gauge “ (no quotes; that’s the word “gauge” with a slash before it and a space afterwards).
- Control-click on “gauge”. You’ll see the regular Cut, Copy, etc menu. The word will also be highlighted.
- Now click outside the word, without choosing any of the contextual menu options. A red wiggly underline will now appear under “/gauge”.
- Control-click “gauge” again, and look at the suggested replacements. You may have to repeat steps 3 and 4 if you don’t see the list.
Can anyone explain what those replacements mean?
