In a set of mutually exclusive tags, the first tag can be defined as a
|
||||
@emph{group tag}. When you search for a group tag, it will return matches
|
||||
for all members in the group. In an agenda view, filtering by a group tag
|
||||
will display headlines tagged with at least one of the members of the
|
||||
group. This makes tag searches and filters even more flexible.
|
||||
|
||||
You can set group tags by inserting a colon between the group tag and other
|
||||
tags, like this:
|
||||
|
||||
@example
|

#+TAGS: @{ @@read : @@read_book @@read_ebook @}

In this example, @samp{@@read} is a @emph{group tag} for a set of three
|

tags: @samp{@@read}, @samp{@@read_book} and @samp{@@read_ebook}.

||||
|

You can also use the @code{:grouptags} keyword directly when setting
