+# List All The Enabled ZSH Options
+
+The zsh shell has a [ton of
+options](https://zsh.sourceforge.io/Doc/Release/Options.html) that can be
+enabled and disabled for all kinds of functionality. Some of these options are
+enabled by default, some of them may be enabled by a script like
+[oh-my-zsh](https://ohmyz.sh/), and even more might have been enabled or
+disabled by you in your `~/.zshrc` file.
+
+To quickly produce a list of all options that are currently enabled, run:
+
+```bash
+$ setopt
+```
+
+All enabled options will be output by that command. That might be a lot of
+output, so if you know what you are looking for, you can `grep` through the
+output. Or, even better, if you have [`fzf`](https://github.com/junegunn/fzf)
+installed, you can interactively fuzzy search through it.
+
+```bash
+$ setopt | fzf
+```
