How to manage user alerts from apps when in the background

[Keith Clarke]

Hi folks,
Can LiveCode alert the user of things such as inbound message when the app is in the background? 

I'm guessing this is all about OS-specific features - notifications on iOS, maybe Growl for OSX and whatever those system tray icons and 'tooltips' are on windows.

If it's possible, where should I start my studying - what's LiveCode feature am I looking for?
Best,
Keith..
