beamer+biblatex：更改 \footcite 的 \footnotemark 样式

Question

是否可以更改（来自 biblatex）\footnotemark创建的样式\footcite，使其看起来更像引用符号？

我想将我的参考文献保留为脚注，但我希望它们看起来更像实际的引用。

\usepackage[backend=bibtex, style=verbose]{biblatex}

注 1：tex.stackexchange.com 上有很多关于更改脚注样式的问题。这是关于脚注标记本身的问题。

笔记2：我不会将脚注用于其他任何用途，因此我不介意直接更改脚注标记，而不管它是否由 footcite 创建。我只是找不到如何以这种方式自定义脚注标记...

Answer 1

由于您不使用脚注进行其他任何操作，因此您可以修改\@makefnmark（这就是所谓的\insertfootnotemark）
