I see that the only allowed characters in tags are letters, numbers, _, and @. While _ apparently serves to visually separate words, why is @ included? Does it have any special meaning, or a typical use case?

  • Many advanced GTD users designate contexts with the @ symbol. I found a blog about it relating to org-mode, but I didn't find a reference in the manual using a cursory Google search.

  • Here is a link to an answer I previously wrote for someone who wanted to highlight contexts differently, and I liked it so much, that I use it now myself: stackoverflow.com/a/40918994/2112489

  • Thanks! To sum it up, there's no special meaning, but it's just practical (emails, locations, etc use it) so it was added. (Too bad - was not.)
