How to remove text services? I know service workflows created from Automator can be removed from ~/Library/Services, but I cannot see any services related to selected text there.

See my screenshots


I must have installed apps that added such services the LaTeX series in the screenshot, which shows up in the context menu when right-clicking text in apps like Notes.

How to remove these services then?
OK, found it myself. Under System Preferences > Keyboard > Shortcuts > Services, I can uncheck those 3rd-party services.
