notes and vocabulary

Hi All

I can't find any information on how to add to the notes and vocab. Help Please

Hi sebongela.  (1) When in a lesson, there is a notes tab in the left-hand blue column.  I enter mine there.  (2) For vocab, I hover over the word, and the is a save pop up.  If hovering doesn't work, just double click the word, and "+ save" pops up.   A presto.  Chris
