Tags are embedded anywhere within the note's contents. They're regular
hashtag-tags, i.e. #psychology
or #biology
, with the restriction that
they're both preceded and succeeded by whitespace.
Subtags are tags which contain one or more forward slashes, i.e.
#psychology/disorders
, #biology/anatomy
, or
#literature/unprocessed/urgent
. These allow you to get more specific with your
tagging, to move from a more abstract subject towards a more concrete idea (or
task).
It's entirely up to you how you organise your tags and subtags, or if you use tags at all.
