By default, the <A-*> key doesn't work in any macOS terminal since all alt-related keys are mapped to the corresponding real character generated. For example (You can try typing these characters yourself!):

<A-g> --> ©
<A-S-p>(upper case `p`) --> ∏ 

There are two solutions, you may choose the one that suits you best 👍

1. Map the Alt key to the corresponding output symbol (e.g., <A-g> --> ©), you may refer to my config for more information. Do note that you need to change two files: lua/keymap/init.lua and lua/core/mapping.lua.
2. Looks like you are using iTerm2. Simply open "Preferences" (⌘,) --> Profiles (select your current profile) --> Keys --> General tab, and set the Left/Right Option key to Esc+. As shown: (Note: In this mode, the modified left/right option key can no longer be used to input symbols in the terminal)
