I'm coding a web-portal for a set top box with a custom keyboard. The keyboard has most of the standard character keys but no backspace! Since there are some other free custom keys, I would like to map one of these to backspace when I'm in an input field or in a text area. The question is: How do I programmatically send a backspace to the input field? Or for that matter: How do I programmatically send any key (like an arrow key) to the input field?
