Maybe a dumb question, but I've never quite figured out how to use `@` properly in opencode's TUI.

I'm used to searching for files with `@` in Codex or Claude Code, but in opencode the behavior seems inconsistent — sometimes it shows a file dropdown, and other times it shows `@explore` or `@general` options instead.

What are those options actually used for, and is there a way to reliably trigger the file dropdown every time?
