如何设置“智能引用命令”？

该biblatex软件包附带了一堆示例文件。其中一个名为18-数字混合.tex。其中包含以下文本：

我们为在线参考文献定义了专用的引文命令，该命令使用数字标签而不是作者年份方案。除了定义专用命令外，还可以（通常更可取）构建智能引文命令，该命令能够根据条目类型（或其他标准）切换引文样式。

有人能提示我如何以最佳方式实现这种智能引用命令吗？

首先，我认为奥黛丽说得对，人们只能猜测上述文件的创建者所说的“智能引用命令”是什么意思。

Audrey 发布的链接帮助我提出了这个 MWE（请注意，我的例子是基于混合风格的想法，如18-数字混合.tex包的示例文件biblatex):

\documentclass{article}
\usepackage[utf8]{inputenc}
\usepackage[T1]{fontenc}
\usepackage[american]{babel}
\usepackage{csquotes}
\usepackage[
    style=alphabetic,
    labelnumber,
    defernumbers,
    backend=biber,
]{biblatex}
\addbibresource{test.bib}

\begin{filecontents}{test.bib}
@BOOK{Author2001,
  author = {Alastname1, Afirstname1},
  title = {Title},
  year = {2001},
}
@BOOK{Author2002,
  author = {Blastname1, Bfirstname1 and Blastname2, Bfirstname2},
  title = {Title},
  year = {2002},
}
@ONLINE{Online2001,
  author = {Olastname1, Ofirstname},
  title = {Test Website},
  year = {2001},
  url = {http://www.test.de},
  urldate = {2013-08-28},
}
@ONLINE{Online2002,
  author = {Olastname2, Ofirstname},
  title = {Test Website},
  year = {2002},
  url = {http://www.test.de},
  urldate = {2013-08-28},
}
\end{filecontents}
