Ah, OK. Basically many terminal emulators allow you to create text that is clickable, with the click going to an arbitrary URL. That could be a URL on the internet, but there are more interesting possibilities: e.g. you click on a line number in your terminal and it opens in your editor / IDE at that line number.
The standard link that started it is https://gist.github.com/egmontkob/eb114294efbcd5adb1944c9f3c..., but if you do internet searches for terms like `terminal hyperlinks ripgrep` or `terminal hyperlinks ls` or `terminal hyperlinks delta` you'll find more.
I was until I started needing things like true colour support and was forced into trying other options. But if you haven’t noticed anything missing or not working with software that you use then Terminal.app is a fine choice
I try alts when they come up since I might like to use the same thing on macOS and Linux, but I've yet to try one that both has the right features and doesn't feel sluggish.
