+This function behaves exactly like @code{error}, except that it uses
+the error symbol @code{user-error} rather than @code{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 @code{Info-history-back} (@kbd{l}) to
+move back beyond the start of your Info browsing history, Emacs
+signals a @code{user-error}.  Such errors do not cause entry to the
+debugger, even when @code{debug-on-error} is non-@code{nil}.
