Using Storyline for simulations on desktop and iphone - using Enter key and Tab Key

Hi there

I am creating a simulation where the user has to type a title and description into a text field. For the desktop version, it is fine - I put a trigger that says the user can press the enter key to continue. 

What my client wants is that when users are using their iPad's they want them to tap the screen to continue instead as there is no Enter option on iPads.

In Adobe Captivate I managed to do this using the javascript blocks built in. It recognised what platform the user was and changed the instructions too.

My question is: Is there a similar option in Articulate or could someone help me with this using JavaScript please?

Many thanks

Simon
