Entire Project? How to create it?

When I insert the object 'touch',

it always says ".... This object is available to the entire project."

How to create the entire project? I have already save as a single file.

Would anybody teach me the steps to create it ?

Do you mean export your finished game ?

you mean that I can insert the object. However, it only works after exporting the game.

"Entire Project" is your project. You will can use "touch" "mouse" or "Keyboard" if add before it. You will see the "keyboard" events only after add "Keyboard" to entire project.

Yeah, it basically means the object needs only to be added once for you to be able to use it on any layout.
