Control keyboard update rates

[herksaw]

For example, how do I control the rate of keyboard check for user inputs, like every ten frames.

You can't really, the browser will fire the event on keypress regardless and there's no way (that I know of) to modify how often this happens, beyond changing your keyboard repeat settings in Windows /  OS X. You can add in an artificial delay so you don't respond to the key press, i.e. you could respond to every 10th press for example (or repeat of a press) but you'd need to code that into your game loop and use an internal timer to keep track. Even with it, the events will still fire from the browser though.
