如何在生成的 pdf 中将参考文献的摘要作为鼠标悬停文本获取？

对于 BibTeX 条目，有一个字段称为，abstract可以输入作品的摘要。在编译的文档中为 BibTeX 文件中每个包含摘要的参考文献添加纯文本摘要会占用最终报告中的大量额外空间，这通常非常不切实际。

另一种方法（不会占用报告中的任何空间）是将每个摘要作为鼠标悬停文本包含在生成的 pdf 中（当然，如果编译为 pdf 的话），当读者将鼠标悬停在包含该摘要的参考文献标题上时，将显示该文本。可以实现吗？

答案1

下面的例子使用 biblatex+biber。

它重新定义了标题格式（\renewbibmacro*{title}{...}），以将引文摘要文本作为工具提示。如果单击标题，则可以移动工具提示。

（需要 Adob​​eReader。）

pdflatex mydoc
biber mydoc
pdflatex mydoc
