10To use option key under macOS as Meta key use the option
11`option_as_alt` and set it to `"Both"`.
12
13This is the example for the newer Toml file format.
14
15```toml
16# ~/.alacritty.toml
17[window]
18option_as_alt = "Both"
19```
20
21And this is the older YAML format.
22
23```yaml
24# ~/.alacritty.yml
25window:
26  option_as_alt: Both
27```
