Last couple of sentences down below may interest you.
,---- From (info "(elisp) Signaling Errors")
|
| -- Function: user-error format-string &rest args
| This function behaves exactly like `error', except that it uses
| the error symbol `user-error' rather than `error'. As the name
| suggests, this is intended to report errors on the part of the
| user, rather than errors in the code itself. For example, if you
| try to use the command `Info-history-back' (`l') to move back
| beyond the start of your Info browsing history, Emacs signals a
| `user-error'. Such errors do not cause entry to the debugger,
| even when `debug-on-error' is non-`nil'. *Note Error
| Debugging::.
