here's a few cool tips I found...
Ctrl+Alt+T = duplicates your transforming
Ctrl+Alt+Shift+N
To create a new layer directly above the one you're using... and then...
Ctrl+Alt+Shift+E
To duplicate every visible layer to the new layer you've just created.
and finally... sketch ideas and layout on your canvas whilst having everything selected (Ctrl+A)... then if you wanna start over cause you screwed up or whatever.... just hit Backspace or Delete to begin again.
