clicking to show and remove text box

My reply comes a bit late but it took me forever to find out an easy way how to make a text box appear when a users clicks a button or an object. I finally managed to find out and it is so easy. 

On the Slide or slide layer where you want the textbox to appear simply click on Insert on the top menu and then select Marker further to the right. Now select any of those markers and position it anywhere on your slide. A text box will appear and you are now able to add text and even images to it. 

on the preview what will happen is that the button will show the text box when you click on it and when you click outside the text box or on the marker button it will close again. 

Hope this helps anyone new looking for a similar solution. Took me quite a while to figure it out as i was not able to find anything online
