keyboard functions in mathematica

I am trying to find out what keyboard functionalities Mathematica has. Would appreciate anyone to 开发者_高级运维give some help. Specifically, I want to:

1) How to implement something like "press any key to continue..." behavior

2) How to accept user input?

Many thanks.

First, you'll want to look at Input and ChoiceDialog for something simple.

If you want to build your own interface, you can use the dynamic interactivity components with CreateDialog to construct a custom notebook dialog window to accept and return whatever kind of input you'd like.

You might find the Introduction to Control Objects and Generalized Input tutorials useful as well.
