Just be aware, that this collides with f{character} and using , to get back to the previous match.

After using f{character} you can type ; to go to the next occurrence of the character or , to go to the previous one.

Although it seems to be consistent with spacemacs, we should document this behavior and its escape hatch (remove that from the settings.json). I am not sure if this should be document in the Major mode page or the troubleshooting page.

Major mode page or the troubleshooting page

Maybe in major mode we mention you can use , to access major mode and we link to the troubleshooting page if the user wants to disable this behavior.

That sounds good. Created a PR with the suggestion.
