Last couple of sentences down below may interest you.

|  -- 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::.
