Powerpoint slide to reveal contents of one part on click - How?

[Guest]

I would like to implement flashcards with powerpoint. There will be three
boxes on every slide. The title box and two text boxes below it. The text
box to the right will hide its contents normally but will reveal on mouse
click. A second mouse click will toggle it back to hiding contents.

Any help will be greatly appreciated.

Set up the right text box with a coloured fill.

Make a rectangle of the same shape and fill.

Do a custom animation for the rectangle to exit > fade

And another for the rectangle to entrance > fade

Trigger the entrance from a click on the textbox and the exit from a click
on the rectangle. Place the rectangle in front of the text box. Done!
