Found the answer in the parent thread, thank you @Quibblekrust@thelemmy.club:
That’s a mention, not a tag. A tag is a private description you save about a user. Only apps have this fearure.
It’s a little weird that they took a well established term (in social media context: tag, id by which to mention a user, also known as ‘tagging’) and gave it a wholly different meaning (tag: label).
I’m afraid to say that I too have been corrupted by VSCode.
It’s widely used, easy to get into, has LOTS of extensions, and works mostly the same across OS’es meaning it’s easy to setup by and explain to others.
The two extensions I’m missing most in other IDE/text editors would be the “Remote - SSH” extension by Microsoft, which gives unparalleled integration when working remote, and PlatformIO which, while it can be used independently in its core form, just works way better in VSCode.
Besides this, I’ll use Nano for small tasks and vi on embedded devices where Nano is unavailable, though, I’ll need a vi cheatsheet for anything more advanced than basic editing.
