Sometimes you need to control Captivate functionality and you struggle finding ways to accomplish your task. In this blog series, we'll be addressing different issues we've encountered personally and popular questions and problems discussed on forums regarding Captivate. Ready? Let's get started.
Have you ever needed to capture a keypress in Captivate? It's easy enough to capture a keypress in Captivate, but how do you capture the incorrect key? Someone recently posted in a Captivate forum that while they were able to capture the correct and incorrect key press entries and branch to slides based on a user's entries, they wanted an easy way to also capture if a user enters something outside of the entries they were evaluating, similar to a Catchall. In this post we'll give you a simple way to capture keypress entries and jump to a slide based on the results.You may find this useful when evaluating user responses to an interaction or use your imagination for ways you could implement this feature.

Line 2 is the function declaration the swf file calls after a keypress.
Line 4 is used to capture the Captivate object in the variable "cp" so we can communicate with Captivate.
Line 6 is the statement if the "A" key is pressed.
Line 8 uses the cpEISetValue function to jump to slide 2 in the presentation.
NOTE: The slide numbering begins with zero. For example: to jump to slide 14 (in the Filmstrip), specify 13 as the value for this variable.
Line 10 is the statement if the "B" key is pressed.
Line 12 uses the cpEISetValue function to jump to slide 3 in the presentation.
Line 14 is the else statement for any other keypress.
Line 16 uses the cpEISetValue function to jump to slide 4 in the presentation.
