If you want to get some input from the user, my God I don't want to have to program it to low level zero and 1 just to get keys from the keyboard; please let there have been someone who does that for me and indeed there are an increasingly sophisticated options that you can pull off the shelf.

如果你想获得一些用户的输入数据，我的上帝,我可不希望在键盘上敲入0，1的低水平方式来编程;,希望有个人能帮我做这件事吧,但是现有的选择,也变得日益复杂了。
