changing the states of a shape in responsive project across the time of slide automatically
hi
i want to change the state of objects in a slide not only by clicking but also by the time of voice .
for example in a timeline slide when the voice speaks about 2000 , i like that the button of 2000 to change to an other color and the text of it to be displayed. and when the voice speaks about next time (for exapmle 2005 ) the button of it to change the color and the text of it appears .
(the texts are in a same shape in diffrent states
the buttoms are seprate from each other)
I don't know if I could get my point or confuse you.
at the end is there any way to change state of shapes during the time in an slide
thanks for your answers
