Using the option key in macOS Terminal

I like using the Meta+left/right to navigate back and forth between words. On macOS by default, no key is mapped to Meta!

Fortunately for me, it is possible to configure the Option key to act as a Meta key. With the Terminal app selected, this can be done by going in to Terminal > Preferences (Cmd+,) > Profiles > Select your profile > Keyboard > Use Option as Meta.
