- (void)clearRecentDocumentURL:(NSURL *)url;
{
    NSArray *recentDocs = [self recentDocumentURLs];
    [self clearRecentDocuments:self];
    
    // Must enumerate backwards to register in the correct order
    for (NSURL *aURL in [recentDocs reverseObjectEnumerator])
    {
        if (![aURL ks_isEqualToURL:url])
        {
            [self noteNewRecentDocumentURL:aURL];
        }
