When Using a Mac - using keystroke Command h, it minimizes browser - how to prevent this using javascript?
Why would you want to prevent that? It’s best not to try to control how people use their computer. Let people make their own choices. 
On press of h we are doing some operations (which is a keyboard shortcut for one of our applications) and it’s working fine in all operating systems except Mac. In Mac window is getting minimized doing so. I need a solution for this problem.
