Comments on Supernotes are quick and easy. Just press the little chat bubble, the second icon along the row at the bottom of a card to get started.
Writing a Comment
Comments have full-markdown support, so you can draw attention to a piece of
code or emphasise your writing. To create a new line, use 'Shift + Enter', and 'Enter' to finish a comment.
Editing / Deleting a Comment
Click on the three dots, beside the timestamp, to edit or delete a comment. You can only do this if you have the correct permission though i.e if you authored a comment or the Card's Author/Moderator. Be careful deleting is permanent - you won't be able to get it back!
