Help button

Here's the final change we did. It just creates a help button, showing what the different functions are.

Thanks again for your pull requests!

As far as this one goes, there is definitely something to be said about making the current keyboard controls easier to understand at a glance. OTOH, I think this particular method, of popping up a whole new "window" with detailed text instructions goes quite a bit too far for inclusion in the basic script.

For one thing, it's a whole new "window", and secondly, it's all in English, which would need to have options for translations to be swapped in.

So while this is a neat idea, I would rather improve the way the current keyboard functions can be understood without adding extra text instructions. Cheers, though!
