In an ebuild the KEYWORDS variable informs in which architectures the ebuild is stable or still in testing phase.
示例
下面的示例包含了一些 KEYWORDS 变量可能的值：
文件
example.ebuildKEYWORDS="alpha amd64 arm arm64 hppa ia64 m68k ~mips ppc ppc64 s390 sh sparc x86 ~sparc-fbsd ~x86-fbsd"
在 /var/db/repos/gentoo/profiles/arch.list 查看 keyword 列表。
上面的示例中，在各种架构前面的 ~ 前缀（波浪线字符串）意思是 该架构正处于 "测试阶段"，还没有准备好用于生产。
特殊的 keywords
除了正常的 KEYWORDS 值之外，Portage 还支持三种特殊的 token。
*— 如果该软件包在所有系统架构都是稳定的，那么它可见。~*— 如果该软件包在所有系统架构都是测试的，那么它可见。**— 这个包总是可见。（完全忽略 KEYWORDS）。
附注
The behavior of ~arch and ~* differ: ~arch includes arch, ~* doesn't include *. To use the most recent version of a package which is marked stable or unstable on any architecture, specify "* ~*".

Using more then one keyword
To use a recent version which is marked stable or unstable on any arch use:
文件
/etc/portage/package.accept_keywordsapp-text/fdftk * ~*
To use a recent version which is marked unstable on your architecture or stable on any arch use:
文件
/etc/portage/package.accept_keywordsapp-text/fdftk ~''arch'' *
Using a package that is released for another architecture only
当指定了 -* KEYWORD，这表示该软件包在所有没有在 KEYWORDS 中列出的系统上都有已知的故障。例如，一个只针对 x86 构建的二进制软件包看起来是这样的：
user $equery meta fdftk* app-text/fdftk [gentoo] Maintainer: robbat2@gentoo.org Maintainer: tex@gentoo.org (Gentoo TeX Project) Upstream: None specified Homepage: http://www.adobe.com/devnet/acrobat/fdftoolkit.html Location: /var/portage/repos/gentoo/app-text/fdftk Keywords: 6.0-r1:0: x86 -* License: Adobe
如果说无论如果都要同意这个软件包，那么像这样使用 package.accept_keywords 中其他的 keyword。
文件
/etc/portage/package.accept_keywordsapp-text/fdftk amd64
