I did some searching and many users recommend Rofi but looking at man rofi-script it seems to just be a list picker. You pick something from the a list and only one thing runs. On Alfred and Raycast you can have interactive extensions which are essentially keyboard navigable UIs.

• One example looking at the Alfred workflow gallery is Reddit Browser, where you select a subreddit from a list and then it shows of lists of posts, you can press cmd enter to go back & select another subreddit.
• Another one lets you ask questions for chatgpt and shows answers right in the launcher (I'm not necessarily looking for AI extensions).
• This Raycast extension lets you search and create Notion pages.
