Hi Nan, grayed out and colour characters would be done using states and not layers. One state would be gray and another state would be colour. A trigger would be made to change the colour of the characters when a plus or minus marker is pressed. The quotes could be done on different layers with another trigger showing the appropriate layer when the marker is pressed. Here is a tutorial on changing states: https://community.articulate.com/series/5/articles/adding-and-editing-states
