How do I add words in My Vocab?

To add a word to "My Vocab", you first need to highlight the word you want, then right click and a little sign will pop up that says "abc"...click it, and a box will pop up that will ask you to add the word and meaning that you want, then press save. After you do that, go into your toolbox and click on My Vocab and it should appear. Gabriela P.C.
