Web Inspector: implement panels history traversal on Cmd+Left/Right.

• Component: Web Inspector (Deprecated)
• Status: RESOLVED FIXED

Patch to follow. I did not put a history object into a separate file, because it was too small. Will do it upon request. Although our poor parsers would need to parse more copyright comments!

I just have a few NITs. Otherwise this patch looks awesome! Great idea.

I think a ternary operator in these cases would read much better here.

  var isBackKey = (isMac ? event.metaKey : event.ctrlKey);

This also seems like such a common task (isn't it used all over?) that it might
be worth putting into a method.

The second parameter might not be required. I know that JavaScriptCore
implements the following "Spidermonkey Extension": (from MDC)

Producing the simpler:

  this._history.splice(this._historyIterator + 1);
