以下是我的 ion.lua 配置文件。Lua 是一门非常复杂的语言，但是您会立刻就明白“--”表示的是注释的开始。

lua 已经出现了大约十年，但它到现在还没有广为人知。它不同于我所了解的其他任何脚本语言，并且我也不是惟一发现它有些难用的 Ion 用户。据说一旦您习惯了使用它，您将获益匪浅。
如果您用清单 1 中的设置与 Ion 2 所附带的默认的 ion.lua 进行比较，您将发现，它们没有太多的不同。我的 ion.lua 主要用来加载已经定制的后继 Lua 文件，稍后您将看到这一点。
我的 draw.lua 文件控制的是 Ion 2 中的绘制选项，它们完全是从 Ion 附带的默认 look-clean.lua 中复制而来，所以在这里没有对它们进行讨论。look-clean.lua 文件有很好的注释，所以，如果您想定制 Ion 的颜色和外观，应该去通读该文件。我在 draw.lua 文件中所做的惟一修改是将帧标题的字体变得更大，因为不管在哪里，我都喜欢大字体（为了让眼睛得到休息，您应该使用所能使用的最大字体）。
全局键绑定位于 tzz-ion-bindings.lua 中。如果您键盘上的具体符号的位置与我的不同，那么您应该重新分配它们。例如，我分配给工作台 0 到 6 的键，在数字键区上，这些数字构成了 3/4 个圆。您可以使用 xev 程序来找出用于重新映射的键的名称。
记住，DEFAULT_MOD 是 Mod1，即普通的 Linux（和大部分 UNIX）系统中的 Alt 键。Alt 键也称为 Meta 键，不过，在 Emacs 中，您当然可以通过 Esc 键来访问 Meta，（而在 Solaris 中，Meta 键看起来像是一颗钻石，Alt 键就只是 Alt 键）。如果您能理解最后一句话，那么您就会赞同我的观点！
