How to make it clear that a value is being changed using keynote

Question

I am using keynote to make a presentation.

Let's say that following 3 lines. And the third line is something like

• We are opening a section for kids
• In June use 20% discout on all kids items
• On all kids items 30 days money back guarantee

Next I want this to happen.

• When I hit next then a big "X" come over slowly on "20%"
• When I hit next then I want "20%" to be replaced by "40%"

How do I do that in keynote. I just purchased keynote so I am using the latest version.

Answer 1

Use the Inspector tool to add build-in and build-out transition to your texts and cross.

You'll have 4 build order steps :

1. cross fade in
2. cross disappear
3. text "20%" disappear
4. text "40%" appear

Play with duration and 'start build' settings to obtain desired effect.
