Hey 👋🏻 Thanks for the PR.

Do you feel strongly about having those in Inquirer? It does still conflict with the search functionality in the select prompt.

Personally I'm leaning towards not re-adding the feature at all.

[jolyndenning]

I am a vim user who tries for home row navigation wherever possible, so I'll probably stay on old version of @inquirer/prompts or use my fork of it, if needed. I was confused and disappointed when a fresh install of a library that uses inquirer broke that behavior for me, due to the dependencies within inquirer being listed with ^ syntax so that the change in behavior happens even without updating the @inquirer/prompts version in package.json.

I don't use the search functionality with the select prompt, and ended up downgrading, pinning, and bundling @inquirer/prompts and its dependencies to be able to continue using the vim bindings. See single-spa/heeler#16 and single-spa/heeler#17

I'm open to bringing it back, but this PR will need some extra work:

1. We should turn off searches if bindings are on
2. We'll need to cover the checkbox prompt as well
