I know about Org’s group tags but like any things in Emacs, I wasn’t using them so they slipped out of my mind. Until today. Today, I saw this Tweet:
#orgtip: This one blew my mind, org mode allows you to create *group tags*, and you’re allowed to use regex too.
This is too cool, personally would of used this if I knew about it sooner. Check it outhttps://t.co/fN0jzCGpjC#emacs #orgmode— Daniel Gopar (@pygopar) January 8, 2021
and it reminded me that they can be really helpful in some use cases. The documentation for them is here but the TL;DR is that you can assign a set of tags to a group and then search for items with any of the tags by searching for the group name.
You can obviously get along without them but for some applications they’re the perfect solution. Take a look at the documentation to get the full story.
