Unclear documentation for delete-p command

[huekoh]

[Problem] For the user guide documentation of delete-p command, it does not state that the command is case-sensitive. This may be confusing unless explicitly stated in the guide to alert users, especially since there are other commands such as find that are more lenient and not case-sensitive, so the user experience especially on first use may be inconsistent.
