zoom in and zoom out

Hi guys

I want to make a guide for my game and its long (actually my game will be an apk file and naturally it should be touch ) and it has a lot of text , so how can i make something that user can zoom in or zoom out for reading the text and i also want to make a scroll bar .please tell it by details and it would be so awesome if you post some pics of the steps.

Thank you

There is a zoom and pan example shipped with C2, you can find it in the new project dialog..

Also I made a scrollbar example not to lona ago, you can probably find it using the search..
