iOS Textbased Mail

Thanks Adobe for this great campaign. My first try of the app and created this shot.

The app is so lightweight, even my mid 2013 MBA can handle it smoothly ( but the preview isn't that good because I am using 1600x1200).

Hope I stand a chance to win a new MBP 13'.

Question: Are there any shortcut combinations to select multiple layers in different groups?
