Scripting updates, guided tour fixes, and more.
Keyboard input can only be held down, if you want to press, you need to call addlistener. In addition, how to realize the mirror image? It's not mentioned in the document! There is also the hope to add the automatic completion of the word behavior. I often type the wrong words when I am not my mother tongue in English. Thank you. Well done!
Mirror/flip is just a negative size, and the set mirrored/flipped actions in the manual describe this. There are events fired for keyboard input, that's the normal way for detecting key presses in JavaScript.
