The Favourites menu, to the left of the headword field, lets you bookmark your favourite dictionary entries for fast access. To add an entry to your favourites while you are consulting it, just click on the Favourites button (). You also have this option in the Favourites menu (when you click on the small black triangle to the right of the heart), in the Edit menu. Then you can access your favourite dictionary entries using the Favourites menu.
To delete an entry from your list of favourites, go to its entry in the dictionary and then click on the Favourites button. Alternatively, open the Favourites window by selecting Edit from the Favourites menu. Then, select Dictionaries from the left-hand panel, select the entries to delete from the right-hand panel, click the three dots in the top right and then choose the option Delete selection. Selecting Delete all will delete them all at once.
To export a list of favourites, open the Favourites window, select the list, click on the three dots and select Export.
You can also manage your favourites by selecting Favourites from the Edit menu.
