什么情况下不应该使用“kbd”？

Emacs-general
1

我一般表示一个键位都用(kbd "<key>")的形式("<key>"指具体的键位)。

而我看到很多人都不这么干，那么什么情况下不该使用kbd？

谢谢

Why not?

不如全部都用kbd。天下大同岂不美哉

因为我是一个没有主见的人，尤其在Emacs配置上

哦，非要说的话，比起直接写键绑定的字面量，用kbd会慢点

我都用kbd，感觉很一致清爽，其他方式那种反斜杠看的很碍眼。

举个例子就是，python 2的print statement和python 3的print，我倾向后者

我现在是一般的键用kbd，需要绑定功能键和特殊键（比如F1～F12，Return之类的）就直接写

用kbd挺好的啊。下面是我自己的初始化文件的节选，所有直接用Vector定义的都是才开始玩Emacs的时候写下的，所有用kbd都是玩了一段时间之后写下的。
