我正在尝试在OS / X上使用Git HEAD版本的Emacs 24，如本文所述：
我想将一些Macintosh扩展键盘数字小键盘键绑定到Emacs功能，但它似乎不起作用。当我执行“c-h k”检查关键细节时，无法识别按键。同上，如果我在（global-set-key（kbd“kp-minus”）...）设置中引用它们。
这是使用Emacs 24的开发版本的问题还是关于Macintosh键盘硬件以及Emacs如何看待它的问题？任何人都可以提出最好的解决方法吗？
提前致谢，
斯图

我在构建emacs 24的键盘按键上遇到了同样的问题。问题与emacs 23相同。我修改了emacs 24代码如下以纠正问题。不确定这是一个很好的解决方案，但对我来说效果还不错。

我尝试使用较旧的Emacs：
这是GNU Emacs 22.2.1（powerpc-apple-darwin9.5.0，GTK + Version 2.10.13）
使用+ gtk + x11的ports collection构建并与X11服务器XQuartz 2.1.6（xorg-server 1.4.2-apple33）一起使用，当我查看C-h l时，我得到了
<kp-0> ... <kp-9>
为数字。和
<kp-enter> <kp-subtract> <kp-multiply> <kp-divide> <kp-equal>
其他键。
我建议使用选项+ gtk和+ x11从MacPorts构建最新的Emacs。
然后我会得到最新的XQuartz并在X11上运行Emacs（我更喜欢这种更原生的构建，因为无论它是否在另一个操作系统上远程运行（通常是通过{{1），Emacs总是表现相同}}或本地。
我将在下周将我的端口升级到最新的Emacs，并为这些添加结果。

这个问题是emacs的Cocoa变种所独有的。 Carbon版本中没有这个问题，即emacs22。我更新了上面发布的补丁，现在效果更好。它可能适用于使用XCode 3的Emacs23代码库。如果您使用XCode 4，像我一样，您将需要使用目前仅在GIT存储库中可用的Emacs24代码库。以下是通过XCode 4构建Emacs24的非常好的描述
