Add "setRenderMode(1);" into the onResize function. Then change between the numbers 0 to 3 (so "setRenderMode(3);" for example) to try the different modes. You may have to resize the window a little each time to make the new mode start but I didn't have to. It's a little annoying that it won't register button presses.

Same question here. I hit all kinds of keys and didn't see any difference.

Yes, it appears that the "any" key is missing on my keyboard.

Is because liveweave cancel key mapping by dfault , you need to click on "Tools" then download and open the "source.html" file manualy.

Try the number keys, 0-9, etc. It's in the onkey function.
