[Bug] Jogging with keyboard causes page to scroll

[iceboundflame]

On http://chilipeppr.com/jarret and /grbl, I noticed that if the window is larger than the page dimensions, jogging with the keyboard scrolls the page, which is kind of jarring. Can we lock the page scroll and capture the arrow keypresses when the jog command is active?

Give it a try, but the way I solve it is by making sure no widgets are off
the page by collapsing unneeded ones.

How about preventing default browser action when the Axes widget is getting focused? For example:

window.addEventListener('keydown', function(e) { // arrow keys
    if([37, 38, 39, 40].indexOf(e.keyCode) > -1) {
        e.preventDefault();
    }
}, false);

That's a great idea. Would it be possible for you to fork the github, make
change, and then do pull request?

Sure! I can create a PR once I confirmed it works from my side. :)
