No worries! Thanks for getting back to me. Without the add-on, it just reads the choice text. Example of how it works with this add-on:
Choice = "Eat apple"
Tooltip = "+5 HP"
When the cursor hovers over the choice, it will read out "Eat apple". The tooltip box will appear but it will not be read out. When the cursor is removed from the choice, it will read out "+5 HP" after the tooltip box disappears. If the cursor moves onto another choice while the tooltip text is being read, it will stop reading the tooltip text. There's a slight pause before it reads the tooltip text, so it's easy to select another choice without realizing there was tooltip text.
I think the way it should work is that when the cursor hovers over the choice, it should read out "Eat apple" followed by "+5 HP". I normally do not use self-voicing while playing, but it seems to me that having to move the cursor away but not onto another choice might be difficult or counter-intuitive.
Note: I was mistaken in my last post about needing to duplicate the text into {alt} tags for it to be read out. I just hadn't realized it wasn't being read out because of the cursor issue.
I hope this helps. Thank you for your time.
